Application: kwin_x11 (5.24.4)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-25-generic x86_64
Windowing System: X11
Distribution: Ubuntu Jammy Jellyfish (development branch)
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
Most of the time kwin works well, but sometimes it crashes and restarts, at this time screen becomes black for several seconds and restores. This is not related to some manual actions, I just use the web browser or other app, and sometimes this happens in random time, about 3-5 time per day.
I've found a lot of crash reports with similar title:
```
Application: KWin (kwin_x11), signal: Aborted
```
But it is too general to decide is this crash a duplicate of other, or not.

Please describe me if I can give you some additional info to investigate the problem.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
