Bug ID: 469472
Summary: KWin stops redrawing content of some windows
Classification: Plasma
Product: kwin
Version: 5.24.7
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: rip...@freakmail.de
Target Milestone: ---
Created attachment 158762

Output of kwin_x11 --replace
SUMMARY
Seemingly randomly, (some) windows are not being drawn any more.
Currently, no Thunderbird windows (main, compose-window) are re-drawn,
Systemsettings start with a black content (title bar is drawn), krunner doesn't
show up. If I bring Thunderbird to the front (by clicking on the entry in the
task manager), the screen does not update correctly, but shows old content
(from a Konsole window that should now be "beneath" Thunderbird in the
graphical stack).
I can still interact with the session, e.g. I'm typing this message, if I bring
Konsole to the front of Thunderbird I can run commands etc.
I can close some windows (e.g. systemsettings), but not Thunderbird (times out,
display is grayed and there should be the dialog from KWin to force quit, but
that dialog is not drawn).
STEPS TO REPRODUCE
1. Sorry, I don't know how to reproduce this
OBSERVED RESULT
Some re-drawing seems to break.
EXPECTED RESULT
KWin should continue to redraw the content of all applications
Operating System: Kubuntu 22.04

ADDITIONAL INFORMATION
I've added some output from kwin_x11 --replace from a Konsole window. I'll
happily add more info if wanted but since I can't reproduce the issue, it might
take a while. I'm also not very familiar with getting more detailed info, if
possible, please be a little detailed in what I have to do to get the requested
info.
I'll attach the log from plasmashell --replace, too, if that's of any help.
