Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

When full screen, and opening(focusing) other programs, wezterm loses position and size.
Screencast from 2023-11-12 17-46-54.webm

To Reproduce

open wezterm
make it full-screen or half screen
focus on other program

Configuration

THIS IS FULL CONFIG

local cfg = {
	window_close_confirmation = "NeverPrompt",
	check_for_updates = false,

	-- Avoid unexpected config breakage
	automatically_reload_config = false,

	exit_behavior = "Close",

	-- Disable all noises
	audible_bell = "Disabled",

	-- remove terminal top bar
	window_decorations = "NONE",

	-- setup color theme
	color_scheme = "Solarized Light (Gogh)",
}
cfg.hide_tab_bar_if_only_one_tab = true

cfg.window_padding = {
	left = 3,
	right = 3,
	top = 3,
	bottom = 3,
}

cfg.inactive_pane_hsb = {
	saturation = 0.9,
	brightness = 0.6,
}

-- set cursor shape to a Blinking Bar
cfg.default_cursor_style = "BlinkingBar"
cfg.animation_fps = 1
cfg.cursor_blink_ease_in = "Constant"
cfg.cursor_blink_ease_out = "Constant"

return cfg

plus some things about font

Expected Behavior

Secondary program gain focus while wezterm keeps its shape

Logs

No response

Anything else?

It's not happening with no configuration

If it helps to solve the problem, also moving the terminal window to another workspace fixes the problem.
Like
opening the terminal
make it full screen
move it to another workspace

[Naadiyaar]

issue solved by removing window_decorations = "NONE" but re-enabling it bring the problem back
any idea what's causing this?

I'm on Arch Linux, GNOME 45.1 (wayland), wezterm 20230712-072601-f4abf8fd and I can't reproduce this, so I wonder if this has been fixed on the GNOME side? Are you able to boot GNOME OS or some other live USB with a newer GNOME to check?

[Naadiyaar]

currently i'm using a fresh install Fedora 39 with GNOME 45.1 and this behavior is easily reproducible on flatpak version and RPM nightly by adding window_decorations = "NONE" to config.
so no it's not fixed here

I was able to reproduce the bug on Fedora 39, latest GNOME and latest WezTerm from flathub.

Replacing window_decorations = "NONE" with window_decorations = "RESIZE" was a workaround for me.

Should be fixed by #5897
