Bug ID: 445677
Summary: Kwin crashes when switching windows using thumbnail
switcher quickly
Product: kwin
Version: 5.23.3
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: nishant....@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.23.3)
Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.14.14-3-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.3 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I was writing some word document with 4 browser tab open and 2 spreadsheet
opened
and I was constantly switching between them. I was also switching between one
activity to other
to change tracks in Spotify. Suddenly Kwin crashed and Activity switching
stopped working (Wallpaper was not
changing, but I can see my apps changing, but there was no visual effect,
furthermore the active application
remained open even though activity changed)
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
