Description Filip Cvejić 2023-09-10 15:18:47 UTC 
Application: elisa (23.04.3)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.2.0-10018-tuxedo x86_64
Windowing System: X11
Distribution: TUXEDO OS 2
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
I have two screens connected to my Zephyrus G14 (2020) running Tuxedo OS 2. Sometimes, on system wake-up, the entire desktop is messed up and the windows are blinking between the two screens. I fix this by disconnecting one of the screens and reconnecting it. Elisa crashed during this process (possibly before disconnecting the screen).

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Elisa (elisa), signal: Segmentation fault
