Description Ralf Jung 2022-10-29 16:53:05 UTC

SUMMARY
When I start a Plasma wayland session, the task manager tooltips do not show window previews. There's just a big empty area where the preview would go. Previews work fine under X11, and in the alt-tab menu they work even under Wayland.


STEPS TO REPRODUCE
1. Open some windows
2. Hover the window entires in the taskbar -- there is no preview

OBSERVED RESULT
See the attached screenshot. (It doesn't make a difference whether the window is minimized or not.)

EXPECTED RESULT
There should be a window preview.
