Description fbm224 2026-03-15 14:59:34 UTC 
Application: plasmashell (6.6.2)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.2
Frameworks Version: 6.23.0
Operating System: Linux 6.19.6-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 6.6.2 [CoredumpBackend]

-- Information about the crash:
I have an issue with panel applets like system tray or the launcher, where the popups fail to show.  See:

https://discuss.kde.org/t/system-tray-mini-apps-not-showing/44916

It can be reproduced by repeatedly and quickly clicking on the applet icon. As mentioned on discuss.kde the behaviour is restored with `systemctl --user restart plasma-plasmashell`, or by switching user, loging out. 

This bug report was launched after restarting plasmashell from the terminal.  I've not been able to reproduce on a new user.

The crash can be reproduced every time.
