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
