[ ] Other (Please describe in detail)

Current Behavior

When the gitk window closes, the terminal window goes back to full-screen but it has no focus and i3 is completely frozen (cannot click the terminal to focus it, cannot type anything on the terminal, cannot start a new terminal, cannot switch desktop, etc...) The system is still running because by pressing CTRL+ALT+F2 I can switch to a console login where I can log and killall i3.

Expected Behavior

The act of quitting gitk shall not freeze i3.

Reproduction Instructions

  1. Start i3 wm.
  2. Open a terminal, which goes full-screen.
  3. From the terminal first cd to a git repo and then start gitk from the command line.
  4. Quit gitk, either with the CTRL-Q shortcut or through the menu File -> Quit.

Environment

Output of i3 --moreversion 2>&-:

# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below.
font pango:monospace 8

# This font is widely installed, provides lots of unicode glyphs, right-to-left
# text rendering and scalability on retina/hidpi displays (thanks to pango).
#font pango:DejaVu Sans Mono 8

# Before i3 v4.8, we used to recommend this one as the default:
# font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, its unicode glyph coverage is limited, the old
# X core fonts rendering does not support right-to-left and this being a bitmap
# font, it doesn’t scale on retina/hidpi displays.

I'm now running the latest stable version (4.15) and the bug still persists.
I updated the figures in the first post above and uploaded a log file as requested.

What do you mean that the terminal "goes fullscreen"? Are you trying to open gitk behind a fullscreened window? Or do you mean that the terminal is the only tiling window in the workspace?

I'm fairly sure this is just the focus issue with tk applications for which there's already a bug. If focus breaks in a fullscreen scenario it might feel like it "crashed".

@orestisf1993, the second one. I'm just using the default layout, i.e. the terminal is the only tiling window in the workspace.

I searched for the keyworks tk and focus but I'm unable to find any related issue.
@Airblader is there any known workaround?

@Airblader Yes, gitk is mentioned in #2722. But shouldn't the problem be fixed with 4.15?

@Airblader, I followed the steps here to setup sur5r repository, which includes v4.15 (see above for the exact version banner).

The issue seems to show up only when the config contains bar mode invisible. If I revert back to the default setting then the behavior is the expected one.
