Description René Serral 2021-06-21 10:53:18 UTC
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
