            Bug ID: 467866
           Summary: KDE window manager crashes when using Qt application
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: dietz at smart-cactus.org
  Target Milestone: ---

Application: konsole (21.12.3)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.2-051502-generic x86_64
Windowing System: Wayland
Distribution: Ubuntu 22.04.2 LTS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I was using Lyx (a Qt application). Nothing special, just writing text, maybe
copy & paste.


Since I switched from X11 to kwin/Wayland/Plasma, the KDE window manager
crashes randomly multiple times a day, when I use various applications. 

These are random crashes, so I can't reproduce them.

I think this could be a secondary crash, since it crashed while flushing the
wayland requests.



-- Backtrace:
Application: Konsole (konsole), signal: Aborted
