Application: kwin_x11 (5.23.4)

Qt Version: 5.15.3
Frameworks Version: 5.89.0
Operating System: Linux 5.15.0-8.1-liquorix-amd64 x86_64
Windowing System: X11

DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Saving in Google Earth Pro. Two monitors, Google Earth Pro is on secondary monitor full screen, but opens windows on primary as well. Multiple Firefox windows open but minimized, Okular, Dolphin, System Monitor, and Filezilla are open but also minimized normally, though occasionally up.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
