Description jc 2020-02-23 13:06:48 UTC

Application: plasmashell (5.18.1)

Qt Version: 5.12.4
Frameworks Version: 5.67.0
Operating System: Linux 5.3.0-40-generic x86_64
Windowing system: Wayland
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
When hovering over a widget or element on the Plasma panel, a small tooltip pops up showing the name of the widget/application and a short description. If, under wayland, you rapidly hover over other elements (moving the cursor left to right over other nearby elements, for instance) Plasma is shown to crash. This is what I was doing when the application crashed.

- Unusual behavior I noticed:
General slowness of widget use under Wayland: The "Application Launcher" is very slow and is sometimes unable to be interacted with outright until Plasma is restarted

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
