Bug 472642

Application: systemsettings (5.27.6)

Qt Version: 5.15.10
Frameworks Version: 5.107.0
Operating System: Linux 6.2.0-10018-tuxedo x86_64
Windowing System: X11
Distribution: TUXEDO OS 2
DrKonqi: 5.27.6 [KCrashBackend]

-- Information about the crash:
Every time i try to launch any of the KDE apps (system settings, konsole) when external monitor is plugged in via Type C dockstation it crashes immediately. When i unplug docking station everything is back to normal. I've tried it with different docking stations from several manufacturers with the same result. When i switch to Nvidia Prime performance mode the apps don't crash anymore but the whole interface is laggy and it's probably a topic for another bug report.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
