            Bug ID: 481218
           Summary: Konsole crashes when turning off monitor
    Classification: Applications
           Product: konsole
           Version: 23.08.4
          Platform: Neon
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kde-bugs at xoft.cz
  Target Milestone: ---

Application: konsole (23.08.4)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.2.0-39-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
Konsole crashes after I turn my monitor back on again (after being turned off
for a while). Weirdly enough, it sometimes survives; when I have multiple
instances of Konsole, only some are affected. I estimate 30 % chance of a crash
for each powercycle of the monitor.

I recently upgraded from an NVidia card to an AMD card, RX 6600. The crash only
happens with the AMD card. I didn't observe the crash with the NVidia card;
however, there were other problems which completely rendered me unable to turn
off monitor, so there hadn't been many chances to observe the behavior in the
first place. I believe I got rid of all the NVidia drivers before observing the
crash.

The crash can be reproduced sometimes.

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