           Summary: Plasma Wayland crashes when using touchscreen gestures
    Classification: Unclassified
           Product: dolphin
           Version: 22.08.1
          Platform: OpenSUSE
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi

  Target Milestone: ---

Application: dolphin (22.08.1)

Qt Version: 5.15.5
Frameworks Version: 5.98.0
Operating System: Linux 5.18.15-2-sd_resume x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
Starting from KDE 5.25.5, plasma or the application directly under, crashes
when using the 3 finger touchscreen gestures for switch desktop, present
windows or desktop grid.

This backtrace is from dolphin, but plasma and all other apps tried crash the
same way. When plasma crashes, it restarts and looses the bug report, so I used
dolphin for the backtrace.

This problem only started with 5.25.5, and only effects wayland with the
builtin 3 finger touchscreen gestures. For example, I can switch desktop with
the trackpad or keyboard shortcut and it works fine. This bug only effects the
3 finger touchscreen gestures.

Also, everything works fine in X11.

I clean installed to a separate drive (with a new user), the problem persists.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
