Duplicating lines in terminal

[Thiago4532]

Since the version 0.28, lines on my terminal are glitching and duplicating.

Normally it happens after resizing the window, but I am not sure if this is the only case. In the video I am using IosevkaTerm Nerd Font size=14, and while I was able to reproduce the same results using Monospace 14, it was not consistent.

It also happens when using text_composition_strategy legacy instead of platform. Later I am going to track the commit that exactly commit that caused this bug.

Kitty Configuration

# vim:fileencoding=utf-8:foldmethod=marker

#: Fonts {{{

#: kitty has very powerful font management. You can configure
#: individual font faces and even specify special fonts for particular
#: characters.

font_family      IosevkaTerm Nerd Font
#font_family Monospace
# bold_font        auto
# italic_font      auto
# bold_italic_font auto

#: You can specify different fonts for the bold/italic/bold-italic
#: variants. To get a full list of supported fonts use the `kitty
#: list-fonts` command. By default they are derived automatically, by
#: the OSes font system. When bold_font or bold_italic_font is set to
#: auto on macOS, the priority of bold fonts is semi-bold, bold,
#: heavy. Setting them manually is useful for font families that have
#: many weight variants like Book, Medium, Thick, etc. For example::

#:     font_family      Operator Mono Book
#:     bold_font        Operator Mono Medium
#:     italic_font      Operator Mono Book Italic
#:     bold_italic_font Operator Mono Medium Italic

#: Font size (in pts)

# force_ltr no

#: kitty does not support BIDI (bidirectional text), however, for RTL
#: scripts, words are automatically displayed in RTL. That is to say,
#: in an RTL script, the words "HELLO WORLD" display in kitty as
#: "WORLD HELLO", and if you try to select a substring of an RTL-
#: shaped string, you will get the character that would be there had
#: the the string been LTR. For example, assuming the Hebrew word
#: ירושלים, selecting the character that on the screen appears to be ם
#: actually writes into the selection buffer the character י.  kitty's
#: default behavior is useful in conjunction with a filter to reverse
#: the word order, however, if you wish to manipulate RTL glyphs, it
#: can be very challenging to work with, so this option is provided to
#: turn it off. Furthermore, this option can be used with the command
#: line program GNU FriBidi
#: <https://github.com/fribidi/fribidi#executable> to get BIDI
#: support, because it will force kitty to always treat the text as
#: LTR, which FriBidi expects for terminals.

# adjust_line_height  0
# adjust_column_width 0

#: Change the size of each character cell kitty renders. You can use
#: either numbers, which are interpreted as pixels or percentages
#: (number followed by %), which are interpreted as percentages of the
#: unmodified values. You can use negative pixels or percentages less
#: than 100% to reduce sizes (but this might cause rendering
#: artifacts).

# adjust_baseline 0

#: Adjust the vertical alignment of text (the height in the cell at
#: which text is positioned). You can use either numbers, which are
#: interpreted as pixels or a percentages (number followed by %),
#: which are interpreted as the percentage of the line height. A
#: positive value moves the baseline up, and a negative value moves
#: them down. The underline and strikethrough positions are adjusted
#: accordingly.

# symbol_map

#: E.g. symbol_map U+E0A0-U+E0A3,U+E0C0-U+E0C7 PowerlineSymbols

#: Map the specified unicode codepoints to a particular font. Useful
#: if you need special rendering for some symbols, such as for
#: Powerline. Avoids the need for patched fonts. Each unicode code
#: point is specified in the form U+<code point in hexadecimal>. You
#: can specify multiple code points, separated by commas and ranges
#: separated by hyphens. symbol_map itself can be specified multiple
#: times. Syntax is::

#:     symbol_map codepoints Font Family Name

# disable_ligatures never

#: Choose how you want to handle multi-character ligatures. The
#: default is to always render them.  You can tell kitty to not render
#: them when the cursor is over them by using cursor to make editing
#: easier, or have kitty never render them at all by using always, if
#: you don't like them. The ligature strategy can be set per-window
#: either using the kitty remote control facility or by defining
#: shortcuts for it in kitty.conf, for example::

     map alt+1 disable_ligatures_in active always
#:     map alt+2 disable_ligatures_in all never
#:     map alt+3 disable_ligatures_in tab cursor

#: Note that this refers to programming ligatures, typically
#: implemented using the calt OpenType feature. For disabling general
#: ligatures, use the font_features setting.

# font_features

#: E.g. font_features none

#: Choose exactly which OpenType features to enable or disable. This
#: is useful as some fonts might have features worthwhile in a
#: terminal. For example, Fira Code Retina includes a discretionary
#: feature, zero, which in that font changes the appearance of the
#: zero (0), to make it more easily distinguishable from Ø. Fira Code
#: Retina also includes other discretionary features known as
#: Stylistic Sets which have the tags ss01 through ss20.

#: For the exact syntax to use for individual features, see the
#: Harfbuzz documentation <https://harfbuzz.github.io/harfbuzz-hb-
#: common.html#hb-feature-from-string>.

#: Note that this code is indexed by PostScript name, and not the font
#: family. This allows you to define very precise feature settings;
#: e.g. you can disable a feature in the italic font but not in the
#: regular font.

#: On Linux, these are read from the FontConfig database first and
#: then this, setting is applied, so they can be configured in a
#: single, central place.

#: To get the PostScript name for a font, use kitty + list-fonts
#: --psnames:

#: .. code-block:: sh

#:     $ kitty + list-fonts --psnames | grep Fira
#:     Fira Code
#:     Fira Code Bold (FiraCode-Bold)
#:     Fira Code Light (FiraCode-Light)
#:     Fira Code Medium (FiraCode-Medium)
#:     Fira Code Regular (FiraCode-Regular)
#:     Fira Code Retina (FiraCode-Retina)

#: The part in brackets is the PostScript name.

#: Enable alternate zero and oldstyle numerals::

#:     font_features FiraCode-Retina +zero +onum

#: Enable only alternate zero::

#:     font_features FiraCode-Retina +zero

#: Disable the normal ligatures, but keep the calt feature which (in
#: this font) breaks up monotony::

#:     font_features TT2020StyleB-Regular -liga +calt

#: In conjunction with force_ltr, you may want to disable Arabic
#: shaping entirely, and only look at their isolated forms if they
#: show up in a document. You can do this with e.g.::

#:     font_features UnifontMedium +isol -medi -fina -init

# box_drawing_scale 0.001, 1, 1.5, 2

#: Change the sizes of the lines used for the box drawing unicode
#: characters These values are in pts. They will be scaled by the
#: monitor DPI to arrive at a pixel value. There must be four values
#: corresponding to thin, normal, thick, and very thick lines.

#: }}}

#: Cursor customization {{{

# cursor #cccccc

#: Default cursor color. If set to the special value none the cursor
#: will be rendered with a "reverse video" effect. It's color will be
#: the color of the text in the cell it is over and the text will be
#: rendered with the background color of the cell.  Note that if the
#: program running in the terminal sets a cursor color, this takes
#: precedence. Also, the cursor colors are modified if the cell
#: background and foreground colors have very low contrast.

# cursor_text_color #111111

#: Choose the color of text under the cursor. If you want it rendered
#: with the background color of the cell underneath instead, use the
#: special keyword: background. Note that if cursor is set to none
#: then this setting is ignored.

cursor_shape block

#: The cursor shape can be one of (block, beam, underline). Note that
#: when reloading the config this will be changed only if the cursor
#: shape has not been set by the program running in the terminal. This
#: sets the default cursor shape. Applications running in the terminal
#: can override it. In particular,
#: https://sw.kovidgoyal.net/kitty/shell-integration/ in kitty sets
#: the cursor shape to beam at shell prompts. You can avoid this by
#: setting shell_integration to no-cursor.

# cursor_beam_thickness 1.5

#: Defines the thickness of the beam cursor (in pts)

# cursor_underline_thickness 2.0

#: Defines the thickness of the underline cursor (in pts)

# cursor_blink_interval -1

#: The interval (in seconds) at which to blink the cursor. Set to zero
#: to disable blinking. Negative values mean use system default. Note
#: that numbers smaller than repaint_delay will be limited to
#: repaint_delay.

# cursor_stop_blinking_after 15.0

#: Stop blinking cursor after the specified number of seconds of
#: keyboard inactivity.  Set to zero to never stop blinking.

#: }}}

#: Scrollback {{{

# scrollback_lines 2000

#: Number of lines of history to keep in memory for scrolling back.
#: Memory is allocated on demand. Negative numbers are (effectively)
#: infinite scrollback. Note that using very large scrollback is not
#: recommended as it can slow down performance of the terminal and
#: also use large amounts of RAM. Instead, consider using
#: scrollback_pager_history_size. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.

# scrollback_pager less --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER

#: Program with which to view scrollback in a new window. The
#: scrollback buffer is passed as STDIN to this program. If you change
#: it, make sure the program you use can handle ANSI escape sequences
#: for colors and text formatting. INPUT_LINE_NUMBER in the command
#: line above will be replaced by an integer representing which line
#: should be at the top of the screen. Similarly CURSOR_LINE and
#: CURSOR_COLUMN will be replaced by the current cursor position or
#: set to 0 if there is no cursor, for example, when showing the last
#: command output.

# scrollback_pager_history_size 0

#: Separate scrollback history size, used only for browsing the
#: scrollback buffer (in MB). This separate buffer is not available
#: for interactive scrolling but will be piped to the pager program
#: when viewing scrollback buffer in a separate window. The current
#: implementation stores the data in UTF-8, so approximatively 10000
#: lines per megabyte at 100 chars per line, for pure ASCII text,
#: unformatted text. A value of zero or less disables this feature.
#: The maximum allowed size is 4GB. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.

# scrollback_fill_enlarged_window no

#: Fill new space with lines from the scrollback buffer after
#: enlarging a window.

# wheel_scroll_multiplier 5.0

#: Modify the amount scrolled by the mouse wheel. Note this is only
#: used for low precision scrolling devices, not for high precision
#: scrolling on platforms such as macOS and Wayland. Use negative
#: numbers to change scroll direction.

# touch_scroll_multiplier 1.0

#: Modify the amount scrolled by a touchpad. Note this is only used
#: for high precision scrolling devices on platforms such as macOS and
#: Wayland. Use negative numbers to change scroll direction.

#: }}}

#: Mouse {{{

# mouse_hide_wait 3.0

#: Hide mouse cursor after the specified number of seconds of the
#: mouse not being used. Set to zero to disable mouse cursor hiding.
#: Set to a negative value to hide the mouse cursor immediately when
#: typing text. Disabled by default on macOS as getting it to work
#: robustly with the ever-changing sea of bugs that is Cocoa is too
#: much effort.

# url_color #0087bd
# url_style curly

#: The color and style for highlighting URLs on mouse-over. url_style
#: can be one of: none, single, double, curly

# open_url_with default

#: The program with which to open URLs that are clicked on. The
#: special value default means to use the operating system's default
#: URL handler.

# url_prefixes http https file ftp gemini irc gopher mailto news git

#: The set of URL prefixes to look for when detecting a URL under the
#: mouse cursor.

# detect_urls yes

#: Detect URLs under the mouse. Detected URLs are highlighted with an
#: underline and the mouse cursor becomes a hand over them. Even if
#: this option is disabled, URLs are still clickable.

# url_excluded_characters

#: Additional characters to be disallowed from URLs, when detecting
#: URLs under the mouse cursor. By default, all characters legal in
#: URLs are allowed.

# copy_on_select no

#: Copy to clipboard or a private buffer on select. With this set to
#: clipboard, simply selecting text with the mouse will cause the text
#: to be copied to clipboard. Useful on platforms such as macOS that
#: do not have the concept of primary selections. You can instead
#: specify a name such as a1 to copy to a private kitty buffer
#: instead. Map a shortcut with the paste_from_buffer action to paste
#: from this private buffer. For example::

#:     map shift+cmd+v paste_from_buffer a1

#: Note that copying to the clipboard is a security risk, as all
#: programs, including websites open in your browser can read the
#: contents of the system clipboard.

# strip_trailing_spaces never

#: Remove spaces at the end of lines when copying to clipboard. A
#: value of smart will do it when using normal selections, but not
#: rectangle selections. always will always do it.

# select_by_word_characters @-./_~?&=%+#

#: Characters considered part of a word when double clicking. In
#: addition to these characters any character that is marked as an
#: alphanumeric character in the unicode database will be matched.

# click_interval -1.0

#: The interval between successive clicks to detect double/triple
#: clicks (in seconds). Negative numbers will use the system default
#: instead, if available, or fallback to 0.5.

# focus_follows_mouse no

#: Set the active window to the window under the mouse when moving the
#: mouse around

# pointer_shape_when_grabbed arrow

#: The shape of the mouse pointer when the program running in the
#: terminal grabs the mouse. Valid values are: arrow, beam and hand

# default_pointer_shape beam

#: The default shape of the mouse pointer. Valid values are: arrow,
#: beam and hand

# pointer_shape_when_dragging beam

#: The default shape of the mouse pointer when dragging across text.
#: Valid values are: arrow, beam and hand

#: Mouse actions {{{

#: Mouse buttons can be remapped to perform arbitrary actions. The
#: syntax for doing so is:

#: .. code-block:: none

#:     mouse_map button-name event-type modes action

#: Where ``button-name`` is one of ``left``, ``middle``, ``right`` or
#: ``b1 ... b8`` with added keyboard modifiers, for example:
#: ``ctrl+shift+left`` refers to holding the ctrl+shift keys while
#: clicking with the left mouse button. The number ``b1 ... b8`` can
#: be used to refer to upto eight buttons on a mouse.

#: ``event-type`` is one ``press``, ``release``, ``doublepress``,
#: ``triplepress``, ``click`` and ``doubleclick``.  ``modes``
#: indicates whether the action is performed when the mouse is grabbed
#: by the program running in the terminal, or not. It can have one or
#: more or the values, ``grabbed,ungrabbed``. ``grabbed`` refers to
#: when the program running in the terminal has requested mouse
#: events. Note that the click and double click events have a delay of
#: click_interval to disambiguate from double and triple presses.

#: You can run kitty with the kitty --debug-input command line option
#: to see mouse events. See the builtin actions below to get a sense
#: of what is possible.

#: If you want to unmap an action map it to ``no-op``. For example, to
#: disable opening of URLs with a plain click::

#:     mouse_map left click ungrabbed no-op

#: .. note::
#:     Once a selection is started, releasing the button that started it will
#:     automatically end it and no release event will be dispatched.

# clear_all_mouse_actions no

#: You can have kitty remove all mouse actions seen up to this point.
#: Useful, for instance, to remove the default mouse actions.

#: Click the link under the mouse or move the cursor

# mouse_map left click ungrabbed mouse_handle_click selection link prompt

#::  First check for a selection and if one exists do nothing. Then
#::  check for a link under the mouse cursor and if one exists, click
#::  it. Finally check if the click happened at the current shell
#::  prompt and if so, move the cursor to the click location. Note
#::  that this requires shell-integration to work.

#: Click the link under the mouse or move the cursor even when grabbed

# mouse_map shift+left click grabbed,ungrabbed mouse_handle_click selection link prompt

#::  Same as above, except that the action is performed even when the
#::  mouse is grabbed by the program running in the terminal.

#: Click the link under the mouse cursor

# mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_handle_click link

#::  Variant with ctrl+shift is present because the simple click based
#::  version has an unavoidable delay of click_interval, to
#::  disambiguate clicks from double clicks.

#: Discard press event for link click

# mouse_map ctrl+shift+left press grabbed discard_event

#::  Prevent this press event from being sent to the program that has
#::  grabbed the mouse, as the corresponding release event is used to
#::  open a URL.

#: Paste from the primary selection

# mouse_map middle release ungrabbed paste_from_selection

#: Start selecting text

# mouse_map left press ungrabbed mouse_selection normal

#: Start selecting text in a rectangle

# mouse_map ctrl+alt+left press ungrabbed mouse_selection rectangle

#: Select a word

# mouse_map left doublepress ungrabbed mouse_selection word

#: Select a line

# mouse_map left triplepress ungrabbed mouse_selection line

#::  Select the entire line

#: Select line from point

# mouse_map ctrl+alt+left triplepress ungrabbed mouse_selection line_from_point

#::  Select from the clicked point to the end of the line

#: Extend the current selection

# mouse_map right press ungrabbed mouse_selection extend

#::  If you want only the end of the selection to be moved instead of
#::  the nearest boundary, use move-end instead of extend.

#: Paste from the primary selection even when grabbed

# mouse_map shift+middle release ungrabbed,grabbed paste_selection
# mouse_map shift+middle press grabbed discard_event

#: Start selecting text even when grabbed

# mouse_map shift+left press ungrabbed,grabbed mouse_selection normal

#: }}}

#: }}}

#: Performance tuning {{{

repaint_delay 3

#: Delay (in milliseconds) between screen updates. Decreasing it,
#: increases frames-per-second (FPS) at the cost of more CPU usage.
#: The default value yields ~100 FPS which is more than sufficient for
#: most uses. Note that to actually achieve 100 FPS you have to either
#: set sync_to_monitor to no or use a monitor with a high refresh
#: rate. Also, to minimize latency when there is pending input to be
#: processed, repaint_delay is ignored.

input_delay 2

#: Delay (in milliseconds) before input from the program running in
#: the terminal is processed. Note that decreasing it will increase
#: responsiveness, but also increase CPU usage and might cause flicker
#: in full screen programs that redraw the entire screen on each loop,
#: because kitty is so fast that partial screen updates will be drawn.

sync_to_monitor no

#: Sync screen updates to the refresh rate of the monitor. This
#: prevents tearing (https://en.wikipedia.org/wiki/Screen_tearing)
#: when scrolling. However, it limits the rendering speed to the
#: refresh rate of your monitor. With a very high speed mouse/high
#: keyboard repeat rate, you may notice some slight input latency. If
#: so, set this to no.

#: }}}

#: Terminal bell {{{

enable_audio_bell no

#: Enable/disable the audio bell. Useful in environments that require
#: silence.

# visual_bell_duration 0.0

#: Visual bell duration. Flash the screen when a bell occurs for the
#: specified number of seconds. Set to zero to disable.

# visual_bell_color none

#: The color used by visual bell. Set to none will fall back to
#: selection background color. If you feel that the visual bell is too
#: bright, you can set it to a darker color.

# window_alert_on_bell yes

#: Request window attention on bell. Makes the dock icon bounce on
#: macOS or the taskbar flash on linux.

# bell_on_tab yes

#: Show a bell symbol on the tab if a bell occurs in one of the
#: windows in the tab and the window is not the currently focused
#: window

# command_on_bell none

#: Program to run when a bell occurs. The environment variable
#: KITTY_CHILD_CMDLINE can be used to get the program running in the
#: window in which the bell occurred.

# bell_path none

#: Path to a sound file to play as the bell sound. If set to none, the
#: system default bell sound is used. Must be in a format supported by
#: the operating systems sound API, such as WAV or OGA on Linux
#: (libcanberra) or AIFF, MP3 or WAV on macOS (NSSound)

#: }}}

#: Window layout {{{

# remember_window_size  yes
# initial_window_width  640
# initial_window_height 400

#: If enabled, the window size will be remembered so that new
#: instances of kitty will have the same size as the previous
#: instance. If disabled, the window will initially have size
#: configured by initial_window_width/height, in pixels. You can use a
#: suffix of "c" on the width/height values to have them interpreted
#: as number of cells instead of pixels.

# enabled_layouts *

#: The enabled window layouts. A comma separated list of layout names.
#: The special value all means all layouts. The first listed layout
#: will be used as the startup layout. Default configuration is all
#: layouts in alphabetical order. For a list of available layouts, see
#: the https://sw.kovidgoyal.net/kitty/overview/#layouts.

# window_resize_step_cells 2
# window_resize_step_lines 2

#: The step size (in units of cell width/cell height) to use when
#: resizing kitty windows in a layout with the keyboard
#: (start_resizing_window). The cells value is used for horizontal
#: resizing and the lines value for vertical resizing.

# window_border_width 0.5pt

#: The width of window borders. Can be either in pixels (px) or pts
#: (pt). Values in pts will be rounded to the nearest number of pixels
#: based on screen resolution. If not specified the unit is assumed to
#: be pts. Note that borders are displayed only when more than one
#: window is visible. They are meant to separate multiple windows.

# draw_minimal_borders yes

#: Draw only the minimum borders needed. This means that only the
#: minimum needed borders for inactive windows are drawn. That is only
#: the borders that separate the inactive window from a neighbor. Note
#: that setting a non-zero window margin overrides this and causes all
#: borders to be drawn.

# window_margin_width 0

#: The window margin (in pts) (blank area outside the border). A
#: single value sets all four sides. Two values set the vertical and
#: horizontal sides. Three values set top, horizontal and bottom. Four
#: values set top, right, bottom and left.

# single_window_margin_width -1

#: The window margin (in pts) to use when only a single window is
#: visible. Negative values will cause the value of
#: window_margin_width to be used instead. A single value sets all
#: four sides. Two values set the vertical and horizontal sides. Three
#: values set top, horizontal and bottom. Four values set top, right,
#: bottom and left.

# window_padding_width 0

#: The window padding (in pts) (blank area between the text and the
#: window border). A single value sets all four sides. Two values set
#: the vertical and horizontal sides. Three values set top, horizontal
#: and bottom. Four values set top, right, bottom and left.

# placement_strategy center

#: When the window size is not an exact multiple of the cell size, the
#: cell area of the terminal window will have some extra padding on
#: the sides. You can control how that padding is distributed with
#: this option. Using a value of center means the cell area will be
#: placed centrally. A value of top-left means the padding will be on
#: only the bottom and right edges.

# active_border_color #00ff00

#: The color for the border of the active window. Set this to none to
#: not draw borders around the active window.

# inactive_border_color #cccccc

#: The color for the border of inactive windows

# bell_border_color #ff5a00

#: The color for the border of inactive windows in which a bell has
#: occurred

# inactive_text_alpha 1.0

#: Fade the text in inactive windows by the specified amount (a number
#: between zero and one, with zero being fully faded).

# hide_window_decorations no

#: Hide the window decorations (title-bar and window borders) with
#: yes. On macOS, titlebar-only can be used to only hide the titlebar.
#: Whether this works and exactly what effect it has depends on the
#: window manager/operating system. Note that the effects of changing
#: this setting when reloading config are undefined.

# window_logo_path none

#: Path to a logo image. Must be in PNG format. Relative paths are
#: interpreted relative to the kitty config directory.  The logo is
#: displayed in a corner of every kitty window. The position is
#: controlled by window_logo_position. Individual windows can be
#: configured to have different logos either using the launch function
#: or the remote-control facility.

# window_logo_position bottom-right

#: Where to position the window logo in the window. The value can be
#: one of: top-left, top, top-right, left, center, right, bottom-left,
#: bottom, bottom-right.

# window_logo_alpha 0.5

#: The amount the logo should be faded into the background. With zero
#: being fully faded and one being fully opaque.

# resize_debounce_time 0.1

#: The time (in seconds) to wait before redrawing the screen when a
#: resize event is received. On platforms such as macOS, where the
#: operating system sends events corresponding to the start and end of
#: a resize, this number is ignored.

# resize_draw_strategy static

#: Choose how kitty draws a window while a resize is in progress. A
#: value of static means draw the current window contents, mostly
#: unchanged. A value of scale means draw the current window contents
#: scaled. A value of blank means draw a blank window. A value of size
#: means show the window size in cells.

# resize_in_steps no

#: Resize the OS window in steps as large as the cells, instead of
#: with the usual pixel accuracy. Combined with an
#: initial_window_width and initial_window_height in number of cells,
#: this option can be used to keep the margins as small as possible
#: when resizing the OS window. Note that this does not currently work
#: on Wayland.

# visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ

#: The list of characters to use for visual window selection (for
#: example for selecting a window to focus with focus_visible_window).
#: The value should be a series of unique numbers or alphabets, case
#: insensitive, from the set [0-9A-Z]. Specify your preference as a
#: string of characters.

confirm_os_window_close 0

#: Ask for confirmation when closing an OS window or a Tab with at

#: Tab bar {{{

# tab_bar_edge bottom

#: Which edge to show the tab bar on, top or bottom

# tab_bar_margin_width 0.0

#: The margin to the left and right of the tab bar (in pts)

# tab_bar_margin_height 0.0 0.0

#: The margin above and below the tab bar (in pts). The first number
#: is the margin between the edge of the OS Window and the tab bar and
#: the second number is the margin between the tab bar and the
#: contents of the current tab.

# tab_bar_style fade

#: The tab bar style, can be one of:

#: fade
#:     Each tab's edges fade into the background color (see tab_fade)
#: slant
#:     Tabs look like the tabs in a physical file
#: separator
#:     Tabs are separated by a configurable separator (see tab_separator)
#: powerline
#:     Tabs are shown as a continuous line with "fancy" separators
#:     (see tab_powerline_style)
#: custom
#:     A user-supplied Python function called draw_tab is loaded from the file
#:     tab_bar.py in the kitty config directory. For examples of how to
#:     write such a function, see the functions named draw_tab_with_* in
#:     kitty's source code: kitty/tab_bar.py. See also `this discussion
#:     <https://github.com/kovidgoyal/kitty/discussions/4447>`_ for examples from
#:     kitty users.
#: hidden
#:     The tab bar is hidden. If you use this, you might want to create a
#:     mapping for the https://sw.kovidgoyal.net/kitty/actions/#select-tab
#:     action which presents you with a list of tabs and allows for easy
#:     switching to a tab.

# tab_bar_align left

#: The horizontal alignment of the tab bar, can be one of: left,
#: center, or right.

# tab_bar_min_tabs 2

#: The minimum number of tabs that must exist before the tab bar is
#: shown

# tab_switch_strategy previous

#: The algorithm to use when switching to a tab when the current tab
#: is closed. The default of previous will switch to the last used
#: tab. A value of left will switch to the tab to the left of the
#: closed tab. A value of right will switch to the tab to the right of
#: the closed tab. A value of last will switch to the right-most tab.

# tab_fade 0.25 0.5 0.75 1

#: Control how each tab fades into the background when using fade for
#: the tab_bar_style. Each number is an alpha (between zero and one)
#: that controls how much the corresponding cell fades into the
#: background, with zero being no fade and one being full fade. You
#: can change the number of cells used by adding/removing entries to
#: this list.

# tab_separator " ┇"

#: The separator between tabs in the tab bar when using separator as
#: the tab_bar_style.

# tab_powerline_style angled

#: The powerline separator style between tabs in the tab bar when
#: using powerline as the tab_bar_style, can be one of: angled,
#: slanted, or round.

# tab_activity_symbol none

#: Some text or a unicode symbol to show on the tab if a window in the
#: tab that does not have focus has some activity. If you want to use
#: leading or trailing spaces surround the text with quotes.

# tab_title_template "{title}"

#: A template to render the tab title. The default just renders the
#: title. If you wish to include the tab-index as well, use something
#: like: {index}: {title}. Useful if you have shortcuts mapped for
#: goto_tab N. If you prefer to see the index as a superscript, use
#: {sup.index}. In addition you can use {layout_name} for the current
#: layout name, {num_windows} for the number of windows in the tab and
#: {num_window_groups} for the number of window groups (not counting
#: overlay windows) in the tab. Note that formatting is done by
#: Python's string formatting machinery, so you can use, for instance,
#: {layout_name[:2].upper()} to show only the first two letters of the
#: layout name, upper-cased. If you want to style the text, you can
#: use styling directives, for example:
#: {fmt.fg.red}red{fmt.fg.default}normal{fmt.bg._00FF00}green
#: bg{fmt.bg.tab}. Similarly, for bold and italic:
#: {fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}.

# active_tab_title_template none

#: Template to use for active tabs, if not specified falls back to
#: tab_title_template.

# active_tab_foreground   #000
# active_tab_background   #eee
# active_tab_font_style   bold-italic
# inactive_tab_foreground #444
# inactive_tab_background #999
# inactive_tab_font_style normal

#: Tab bar colors and styles

# tab_bar_background none

#: Background color for the tab bar. Defaults to using the terminal
#: background color.

# tab_bar_margin_color none

#: Color for the tab bar margin area. Defaults to using the terminal
#: background color.

#: }}}

#: Color scheme {{{

# foreground #dddddd
# background #000000

#: The foreground and background colors

background_opacity 0.90

#: The opacity of the background. A number between 0 and 1, where 1 is
#: opaque and 0 is fully transparent.  This will only work if
#: supported by the OS (for instance, when using a compositor under
#: X11). Note that it only sets the background color's opacity in
#: cells that have the same background color as the default terminal
#: background. This is so that things like the status bar in vim,
#: powerline prompts, etc. still look good.  But it means that if you
#: use a color theme with a background color in your editor, it will
#: not be rendered as transparent.  Instead you should change the
#: default background color in your kitty config and not use a
#: background color in the editor color scheme. Or use the escape
#: codes to set the terminals default colors in a shell script to
#: launch your editor.  Be aware that using a value less than 1.0 is a
#: (possibly significant) performance hit.  If you want to dynamically
#: change transparency of windows set dynamic_background_opacity to
#: yes (this is off by default as it has a performance cost). Changing
#: this setting when reloading the config will only work if
#: dynamic_background_opacity was enabled in the original config.

# background_image none

#: Path to a background image. Must be in PNG format.

# background_image_layout tiled

#: Whether to tile, scale or clamp the background image. The value can
#: be one of tiled, mirror-tiled, scaled, clamped.

# background_image_linear no

#: When background image is scaled, whether linear interpolation
#: should be used.

# dynamic_background_opacity no

#: Allow changing of the background_opacity dynamically, using either
#: keyboard shortcuts (increase_background_opacity and
#: decrease_background_opacity) or the remote control facility.
#: Changing this setting by reloading the config is not supported.

# background_tint 0.0

#: How much to tint the background image by the background color. The
#: tint is applied only under the text area, not margin/borders. Makes
#: it easier to read the text. Tinting is done using the current
#: background color for each window. This setting applies only if
#: background_opacity is set and transparent windows are supported or
#: background_image is set.

# dim_opacity 0.75

#: How much to dim text that has the DIM/FAINT attribute set. One
#: means no dimming and zero means fully dimmed (i.e. invisible).

# selection_foreground #000000
# selection_background #fffacd

#: The foreground and background colors for text selected with the
#: mouse. Setting both of these to none will cause a "reverse video"
#: effect for selections, where the selection will be the cell text
#: color and the text will become the cell background color. Setting
#: only selection_foreground to none will cause the foreground color
#: to be used unchanged. Note that these colors can be overridden by
#: the program running in the terminal.

#: Advanced {{{

# shell .

#: The shell program to execute. The default value of . means to use
#: whatever shell is set as the default shell for the current user.
#: Note that on macOS if you change this, you might need to add
#: --login and --interactive to ensure that the shell starts in
#: interactive mode and reads its startup rc files.

# editor .

#: The terminal editor (such as ``vim`` or ``nano``) to use when
#: editing the kitty config file or similar tasks.

#: The default value of . means to use the environment variables
#: VISUAL and EDITOR in that order. If these variables aren't set,
#: kitty will run your shell (``$SHELL -l -i -c env``) to see if your
#: shell config files set VISUAL or EDITOR. If that doesn't work,
#: kitty will cycle through various known editors (``vim``, ``emacs``,
#: etc) and take the first one that exists on your system.

# close_on_child_death no

#: Close the window when the child process (shell) exits. If no (the
#: default), the terminal will remain open when the child exits as
#: long as there are still processes outputting to the terminal (for
#: example disowned or backgrounded processes). If yes, the window
#: will close as soon as the child process exits. Note that setting it
#: to yes means that any background processes still using the terminal
#: can fail silently because their stdout/stderr/stdin no longer work.

# allow_remote_control no

#: Allow other programs to control kitty. If you turn this on other
#: programs can control all aspects of kitty, including sending text
#: to kitty windows, opening new windows, closing windows, reading the
#: content of windows, etc.  Note that this even works over ssh
#: connections. You can chose to either allow any program running
#: within kitty to control it, with yes or only programs that connect
#: to the socket specified with the kitty --listen-on command line
#: option, if you use the value socket-only. The latter is useful if
#: you want to prevent programs running on a remote computer over ssh
#: from controlling kitty. Reloading the config will not affect this
#: setting.

# listen_on none

#: Tell kitty to listen to the specified unix/tcp socket for remote
#: control connections. Note that this will apply to all kitty
#: instances. It can be overridden by the kitty --listen-on command
#: line flag. This option accepts only UNIX sockets, such as
#: unix:${TEMP}/mykitty or (on Linux) unix:@mykitty. Environment
#: variables are expanded. If {kitty_pid} is present then it is
#: replaced by the PID of the kitty process, otherwise the PID of the
#: kitty process is appended to the value, with a hyphen. This option
#: is ignored unless you also set allow_remote_control to enable
#: remote control. See the help for kitty --listen-on for more
#: details. Changing this option by reloading the config is not
#: supported.

# env

#: Specify environment variables to set in all child processes. Note
#: that environment variables are expanded recursively, so if you
#: use::

#:     env MYVAR1=a
#:     env MYVAR2=${MYVAR1}/${HOME}/b

#: The value of MYVAR2 will be a/<path to home directory>/b. Using
#: VAR= will set it to the empty string and using just VAR will delete
#: the variable from the child process' environment.

# watcher

#: Path to python file which will be loaded for
#: https://sw.kovidgoyal.net/kitty/launch/#watchers. Can be specified
#: more than once to load multiple watchers. The watchers will be
#: added to every kitty window. Relative paths are resolved relative
#: to the kitty config directory. Note that reloading the config will
#: only affect windows created after the reload.

# exe_search_path

#: Control where kitty looks to find programs to run. The default
#: search order is: First search the system wide PATH, then
#: ~/.local/bin and ~/bin. If not still not found, the PATH defined in
#: the login shell after sourcing all its startup files is tried.
#: Finally, if present, the PATH in the env option is tried.

#: This option allows you to prepend, append, or remove paths from
#: this search order. It can be specified multiple times for multiple
#: paths. A simple path will be prepended to the search order. A path
#: that starts with the + sign will be append to the search order,
#: after ~/bin above. A path that starts with the - sign will be
#: removed from the entire search order. For example::

#:     exe_search_path /some/prepended/path
#:     exe_search_path +/some/appended/path
#:     exe_search_path -/some/excluded/path

# update_check_interval 24

#: Periodically check if an update to kitty is available. If an update
#: is found a system notification is displayed informing you of the
#: available update. The default is to check every 24 hrs, set to zero
#: to disable. Changing this option by reloading the config is not
#: supported.

# startup_session none

#: Path to a session file to use for all kitty instances. Can be
#: overridden by using the kitty --session command line option for
#: individual instances. See
#: https://sw.kovidgoyal.net/kitty/overview/#startup-sessions in the
#: kitty documentation for details. Note that relative paths are
#: interpreted with respect to the kitty config directory. Environment
#: variables in the path are expanded. Changing this option by
#: reloading the config is not supported.

# clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask

#: Allow programs running in kitty to read and write from the
#: clipboard. You can control exactly which actions are allowed. The
#: set of possible actions is: write-clipboard read-clipboard write-
#: primary read-primary read-clipboard-ask read-primary-ask. The
#: default is to allow writing to the clipboard and primary selection
#: and to ask for permission when a program tries to read from the
#: clipboard. Note that disabling the read confirmation is a security
#: risk as it means that any program, even one running on a remote
#: server via SSH can read your clipboard. See also
#: clipboard_max_size.

# clipboard_max_size 64

#: The maximum size (in MB) of data from programs running in kitty
#: that will be stored for writing to the system clipboard. See also
#: clipboard_control. A value of zero means no size limit is applied.

# file_transfer_confirmation_bypass

#: A password, that can be supplied to the file transfer kitten to
#: skip the transfer confirmation prompt. This should only be used
#: when initiating transfers from trusted computers, over trusted
#: networks or encrypted transports, as it allows programs running on
#: the remote machine to read/write to the local filesystem, without
#: permission.

# allow_hyperlinks yes

#: Process hyperlink (OSC 8) escape sequences. If disabled OSC 8
#: escape sequences are ignored. Otherwise they become clickable
#: links, that you can click by with the mouse or the hints kitten
#: </kittens/hints>. The special value of ``ask`` means that kitty
#: will ask before opening the link when clicked.

shell_integration no-cursor
#shell_integration disabled

#: Enable shell integration on supported shells. This enables features
#: such as jumping to previous prompts, browsing the output of the
#: previous command in a pager, etc. on supported shells.  Set to
#: ``disabled`` to turn off shell integration, completely. See
#: https://sw.kovidgoyal.net/kitty/shell-integration/ for details.

# term xterm-kitty

#: The value of the TERM environment variable to set. Changing this
#: can break many terminal programs, only change it if you know what
#: you are doing, not because you read some advice on Stack Overflow
#: to change it. The TERM variable is used by various programs to get
#: information about the capabilities and behavior of the terminal. If
#: you change it, depending on what programs you run, and how
#: different the terminal you are changing it to is, various things
#: from key-presses, to colors, to various advanced features may not
#: work. Changing this option by reloading the config will only affect
#: newly created windows.

#: }}}

#: OS specific tweaks {{{

# wayland_titlebar_color system

#: Change the color of the kitty window's titlebar on Wayland systems
#: with client side window decorations such as GNOME. A value of
#: system means to use the default system color, a value of background
#: means to use the background color of the currently active window
#: and finally you can use an arbitrary color, such as #12af59 or red.

# macos_titlebar_color system

#: Change the color of the kitty window's titlebar on macOS. A value
#: of system means to use the default system color, light or dark can
#: also be used to set it explicitly. A value of background means to
#: use the background color of the currently active window and finally
#: you can use an arbitrary color, such as #12af59 or red. WARNING:
#: This option works by using a hack, as there is no proper Cocoa API
#: for it. It sets the background color of the entire window and makes
#: the titlebar transparent. As such it is incompatible with
#: background_opacity. If you want to use both, you are probably
#: better off just hiding the titlebar with hide_window_decorations.

# macos_option_as_alt no

#: Use the option key as an alt key. With this set to no, kitty will
#: use the macOS native Option+Key = unicode character behavior. This
#: will break any Alt+key keyboard shortcuts in your terminal
#: programs, but you can use the macOS unicode input technique. You
#: can use the values: left, right, or both to use only the left,
#: right or both Option keys as Alt, instead. Changing this setting by
#: reloading the config is not supported.

# macos_hide_from_tasks no

#: Hide the kitty window from running tasks (⌘+Tab) on macOS. Changing
#: this setting by reloading the config is not supported.

# macos_quit_when_last_window_closed no

#: Have kitty quit when all the top-level windows are closed. By
#: default, kitty will stay running, even with no open windows, as is
#: the expected behavior on macOS.

# macos_window_resizable yes

#: Disable this if you want kitty top-level (OS) windows to not be
#: resizable on macOS. Changing this setting by reloading the config
#: will only affect newly created windows.

# macos_thicken_font 0

#: Draw an extra border around the font with the given width, to
#: increase legibility at small font sizes. For example, a value of
#: 0.75 will result in rendering that looks similar to sub-pixel
#: antialiasing at common font sizes.

# macos_traditional_fullscreen no

#: Use the traditional full-screen transition, that is faster, but
#: less pretty.

# macos_show_window_title_in all

#: Show or hide the window title in the macOS window or menu-bar. A
#: value of window will show the title of the currently active window
#: at the top of the macOS window. A value of menubar will show the
#: title of the currently active window in the macOS menu-bar, making
#: use of otherwise wasted space. all will show the title everywhere
#: and none hides the title in the window and the menu-bar.

# macos_custom_beam_cursor no

#: Enable/disable custom mouse cursor for macOS that is easier to see
#: on both light and dark backgrounds. WARNING: this might make your
#: mouse cursor invisible on dual GPU machines. Changing this setting
#: by reloading the config is not supported.

# linux_display_server auto

#: Choose between Wayland and X11 backends. By default, an appropriate
#: backend based on the system state is chosen automatically. Set it
#: to x11 or wayland to force the choice. Changing this setting by
#: reloading the config is not supported.

#: }}}

#: Keyboard shortcuts {{{

#: Keys are identified simply by their lowercase unicode characters.
#: For example: ``a`` for the A key, ``[`` for the left square bracket
#: key, etc. For functional keys, such as ``Enter or Escape`` the
#: names are present at https://sw.kovidgoyal.net/kitty/keyboard-
#: protocol/#functional-key-definitions. For a list of modifier names,
#: see: GLFW mods <https://www.glfw.org/docs/latest/group__mods.html>

#: On Linux you can also use XKB key names to bind keys that are not
#: supported by GLFW. See XKB keys
#: <https://github.com/xkbcommon/libxkbcommon/blob/master/include/xkbcommon/xkbcommon-
#: keysyms.h> for a list of key names. The name to use is the part
#: after the XKB_KEY_ prefix. Note that you can only use an XKB key
#: name for keys that are not known as GLFW keys.

#: Finally, you can use raw system key codes to map keys, again only
#: for keys that are not known as GLFW keys. To see the system key
#: code for a key, start kitty with the kitty --debug-input option.
#: Then kitty will output some debug text for every key event. In that
#: text look for ``native_code`` the value of that becomes the key
#: name in the shortcut. For example:

#: .. code-block:: none

#:     on_key_input: glfw key: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'

#: Here, the key name for the A key is 0x61 and you can use it with::

#:     map ctrl+0x61 something

#: to map ctrl+a to something.

#: You can use the special action no_op to unmap a keyboard shortcut
#: that is assigned in the default configuration::

#:     map kitty_mod+space no_op

#: If you would like kitty to completely ignore a key event, not even
#: sending it to the program running in the terminal, map it to
#: discard_event::

#:     map kitty_mod+f1 discard_event

#: You can combine multiple actions to be triggered by a single
#: shortcut, using the syntax below::

#:     map key combine <separator> action1 <separator> action2 <separator> action3 ...

#: For example::

#:     map kitty_mod+e combine : new_window : next_layout

#: this will create a new window and switch to the next available
#: layout

#: You can use multi-key shortcuts using the syntax shown below::

#:     map key1>key2>key3 action

#: For example::

#:     map ctrl+f>2 set_font_size 20

#: The full list of actions that can be mapped to key presses is
#: available here </actions>.

# kitty_mod ctrl+shift

#: The value of kitty_mod is used as the modifier for all default
#: shortcuts, you can change it in your kitty.conf to change the
#: modifiers for all the default shortcuts.

# clear_all_shortcuts no

#: You can have kitty remove all shortcut definition seen up to this
#: point. Useful, for instance, to remove the default shortcuts.

# action_alias

#: E.g. action_alias launch_tab launch --type=tab --cwd=current

#: Define aliases to avoid repeating the same options in multiple
#: mappings. Aliases can be defined for any action. Aliases are
#: expanded recursively. For example, the above alias allows you to
#: create mappings to launch a new tab in the current working
#: directory without duplication::

#:     map f1 launch_tab vim
#:     map f2 launch_tab emacs

#: Similarly, to alias kitten invocation::

#:     action_alias hints kitten hints --hints-offset=0

# kitten_alias

#: E.g. kitten_alias hints hints --hints-offset=0

#: Like action_alias above but, specifically for kittens. Generally,
#: prefer to use action_alias. This option is a legacy version,
#: present for backwards compatibility. It causes all invocations of
#: the aliased kitten to be substituted. So the example above will
#: cause all invocations of the hints kitten to have the --hints-
#: offset=0 option applied.

#: Clipboard {{{

#: Copy to clipboard

# map kitty_mod+c copy_to_clipboard

#::  There is also a copy_or_interrupt action that can be optionally
#::  mapped to Ctrl+c. It will copy only if there is a selection and

#::  previous git command.

#: Open selected path

# map kitty_mod+p>shift+f kitten hints --type path

#::  Select a path/filename and open it with the default open program.

#: Insert selected line

# map kitty_mod+p>l kitten hints --type line --program -

#::  Select a line of text and insert it into the terminal. Use for
#::  the output of things like: ls -1

#: Insert selected word

#: Reset the terminal

# map kitty_mod+delete clear_terminal reset active
# map opt+cmd+r        clear_terminal reset active

#::  You can create shortcuts to clear/reset the terminal. For
#::  example::

#::      # Reset the terminal
#::      map kitty_mod+f9 clear_terminal reset active
#::      # Clear the terminal screen by erasing all contents
#::      map kitty_mod+f10 clear_terminal clear active

#::      map kitty_mod+f11 clear_terminal scrollback active
#::      # Scroll the contents of the screen into the scrollback
#::      map kitty_mod+f12 clear_terminal scroll active

#::  If you want to operate on all windows instead of just the current
#::  one, use all instead of active.

#::  It is also possible to remap Ctrl+L to both scroll the current
#::  screen contents into the scrollback buffer and clear the screen,
#::  instead of just clearing the screen, for example, for ZSH add the
#::  following to ~/.zshrc:

#::  .. code-block:: sh

#::      scroll-and-clear-screen() {
#::          printf '\n%.0s' {1..$LINES}
#::          zle clear-screen

#::      bindkey '^l' scroll-and-clear-screen

#: Reload kitty.conf

# map kitty_mod+f5 load_config_file
# map ctrl+cmd+,   load_config_file

#::  Reload kitty.conf, applying any changes since the last time it
#::  was loaded. Note that a handful of settings cannot be dynamically
#::  changed and require a full restart of kitty.  You can also map a
#::  keybinding to load a different config file, for example::

#::      map f5 load_config /path/to/alternative/kitty.conf

#::  Note that all setting from the original kitty.conf are discarded,
#::  in other words the new conf settings *replace* the old ones.

#: Debug kitty configuration

# map kitty_mod+f6 debug_config
# map opt+cmd+,    debug_config

#::  Show details about exactly what configuration kitty is running
#::  with and its host environment. Useful for debugging issues.

#: Send arbitrary text on key presses

#::  E.g. map ctrl+shift+alt+h send_text all Hello World

#::  You can tell kitty to send arbitrary (UTF-8) encoded text to the
#::  client program when pressing specified shortcut keys. For
#::  example::

#::      map ctrl+alt+a send_text all Special text

#::  This will send "Special text" when you press the ctrl+alt+a key
#::  combination.  The text to be sent is a python string literal so
#::  you can use escapes like \x1b to send control codes or \u21fb to
#::  send unicode characters (or you can just input the unicode
#::  characters directly as UTF-8 text). The first argument to
#::  send_text is the keyboard modes in which to activate the
#::  shortcut. The possible values are normal or application or kitty
#::  or a comma separated combination of them.  The special keyword
#::  all means all modes. The modes normal and application refer to
#::  the DECCKM cursor key mode for terminals, and kitty refers to the
#::  special kitty extended keyboard protocol.

#::  Another example, that outputs a word and then moves the cursor to
#::  the start of the line (same as pressing the Home key)::

#::      map ctrl+alt+a send_text normal Word\x1b[H
#::      map ctrl+alt+a send_text application Word\x1bOH

I doubt very much that this is a rendering issue. Most likely it is zsh
(or whatever shell you are using) getting confused after a resize.
Easily checked by pressing ctrl+shift+h to view the screen in a pager.
And runningthe clear or perhaps reset commands in the shell will fix it.

[Thiago4532]

Yeah that was my first thought too, but if you see at 0:20 in the video I cleared the terminal and the glitch was still there. And it only started to happen after 0.28.

I am almost sure that I was able to reproduce this in Bash too, tomorrow I am gonna do more tests just to make sure.

[kovidgoyal]

Press ctrl+shift+h and use reset not clear.

[sidju]

I believe I have this same issue only on my laptop, all my other devices are fine. I trigger it nearly instantly when running an application in raw mode that often sends chunks of print and move escape codes, if that is any indication.

It seems to me the "Clear screen from cursor down" escape code isn't being handled in my case.
Nvm. It's dropping more operations, both escape codes and print, than that.

[kovidgoyal]

I need a reproducer. You can run kitty --dump-bytes and post the dump file after doing a minimal amount to reproduce the issue.

[Thiago4532]

I traced down the commit that was causing the issue and found a buffer overflow at #5664. I made a PR fixing the buffer overflow.
