Description g111 2021-05-28 17:06:46 UTC 
SUMMARY
In a former KDE version (that came with kubuntu 20.10) it was possible to highlight the related window on the desktop when hovering over an entry in the textual list of windows of a window group. All other windows were set transparent so you could see the related window.

In the current version (kubuntu 21.04, plasma 5.21.4) this is not possible anymore.

STEPS TO REPRODUCE
1. configure the task manager to group windows of the same application.
2. configure the task manager to show the textual list of window entries when clicking on a grouped window button.
3. open e.g. 3 konsole windows.
4. open another bigger application window (like thunderbird or something) that covers the konsole windows.
5. click on the grouped konsole window button in the task manager.
6. hover the mouse on one of the entries.

OBSERVED RESULT
Nothing happens.

EXPECTED RESULT
The related konsole window should be shown on the desktop and all other windows should be set to be transparent.

Can reproduce.
Comment 2 Bharadwaj Raju 2021-06-09 07:48:07 UTC 
I can make it highlight the windows, but then the textual list disappears for the duration of the highlight.

This can be fixed by making it a tooltip, but then keyboard navigation doesn't work, which is a much worse regression. Probably because tooltip implies WindowDoesNotAcceptFocus flag.

Any way of having keyboard focus enabled *and* having the list visible?
Comment 3 Nate Graham 2021-06-09 15:04:11 UTC 
The fact that the tooltips can't get keyboard focus is really a bug that needs to be fixed if only for accessibility reasons. Fixing that would be better then working around it.
