Bug ID: 484830
Summary: Program windows of some crashed processes persist
Classification: Plasma
Product: kwin
Version: 6.0.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: w...@toki.la
Target Milestone: ---
SUMMARY
On occasion, windows of crashed processes stick around.
STEPS TO REPRODUCE
1. Cause the "Apostrophe" GNOME app to crash. (This is likely not
reproducible.)
2. Select "Terminate Apostrophe" when prompted.
OBSERVED RESULT
Observe that while the app terminates - it is no longer listed as a running
process - its window persists. Further prompts to terminate the app can be
elicited by repeatedly trying to close it. (They reference a process ID that no
longer exists.) The window is not resizable, and attempting to do so results in
strange temporary artificating, but it can be moved around.
EXPECTED RESULT
KWin recognizes that the process terminated and closes the window.
SOFTWARE/OS VERSIONS
Linux: 6.6.21
KDE Plasma Version: 6.0.2
KDE Frameworks Version: unclear
Qt Version: 6.6.2
ADDITIONAL INFORMATION
I suspect this is weird behavior around programs with client-side
decorations... or perhaps something strange around GNOME as a whole. It is very
strange that KWin doesn't recognize that the program has closed when the rest
of the system does, but I don't know how it's checking for that.
