            Bug ID: 438987
           Summary: Latte Dock randomly crashes on wayland
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: rserral at gmail.com
  Target Milestone: ---

Application: latte-dock (0.9.12)

Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.12.10-300.fc34.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.1
Distribution: "Fedora release 34 (Thirty Four)"

-- Information about the crash:
- Unusual behavior I noticed:

Since migrating to Fedora 34, plasma on Wayland behaves erratically. In
particular latte-dock crashes frequently on random events (not sure if
related):
- Opening new applications
- Closing running apps
- changing windows

The crash can be reproduced sometimes.

-- Backtrace:
Application: Latte Dock (latte-dock), signal: Segmentation fault
