Bug 436981

Application: konsole (21.04.0)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.2-zen2-1-zen x86_64
Windowing System: Wayland
Drkonqi Version: 5.21.5
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
Connecting the dock and trying to force the secondary screen to work, by disabling and reenabling it in the systemsettings

- Unusual behavior I noticed:
The screen was supposedly detected by linux, and yet it stayed off

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
