Bug ID: 399675
Summary: Plasma freezes on mouseover icons in the system tray
and digital clock
Product: plasmashell
Version: 5.13.90
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-wayland
Assignee: plasma-b...@kde.org
Reporter: bugsefor...@gmx.com
Target Milestone: 1.0
Created attachment 115575
--> https://bugs.kde.org/attachment.cgi?id=115575&action=edit
screenshot showing corrupted tooltip of the digital clock
I do not know specific steps to reproduce, but this problem
already happened twice at least on neon dev unstable under Wayland.
When I move cursor on icons in the system tray and digital clock, the tooltip
of the digital clock gets corrupted (see the screenshot) and
plasma freezes. Mouse click on panel, wallpaper or icons on desktop have no
effect.
