Description dezifit 2020-11-09 10:49:27 UTC

SUMMARY
Switching the virtual desktop randomly causes the active window(s) to loose input focus. Unrelated to setting of "Focus stealing prevention".

STEPS TO REPRODUCE
1. Prepare setting with 2 or more virtual desktops
2. Assign one or more windows to each desktop
3. Set (keyboard) input focus to one window
4. Switch virtual desktop and immediately switch it back (with keyboard shortcut)

OBSERVED RESULT
Most of the time the window with input focus before has the focus after a switch cycle. Quite often it has not. 

EXPECTED RESULT
Input focus should stay reliable on the previously selected window after the virtual desktop is switched back.

KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.75.0
