Qt Version: 5.15.3
Frameworks Version: 5.93.0

Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
This bug has been happening fairly frequently; I have a bash script that I run, from Yakuake, which connects to a vpn, checks out and pulls a number of git repos, and then runs some make commands which build a number of services in containers. 

It all works fine, but in about 50% of the cases, the monitor that Yakuake is open in crashes when I run the script. The script runs successfully. When I unplug and re-plug-in the monitor, it works, but the background is black. 

It's not a huge problem, just somewhat inconvenient.

The crash can be reproduced sometimes.

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