SUMMARY Task switcher starts from second task when active screen is changed by mouse moves instead of clicks. As a result, the third task is brought to front by Alt-Tab while it should have switched between the first 2 tasks. STEPS TO REPRODUCE 1. Enable 'Active screen follows mouse' in System Settings -> Window Management -> Window Behaviour 2. Set Task Switcher filters in System Settings -> Window Management -> Task Switcher to: Virtual desktops => Current desktop Activities => Current activity Screens => Current screen Minimisation => Visible windows (this one shouldn't matter tho) 3. Set up 2 or more screens 4. Open at least 3 windows in 1st screen, another in 2nd 5. Click to focus a window in 1st screen 6. Click to focus a window in 2nd screen 7. Without any clicks, move mouse cursor from 2nd screen to 1st 8. Alt-Tab (optionally keep Alt pressed down to see visualisation) OBSERVED RESULT 3rd window in 1st screen is brought to front. EXPECTED RESULT 2nd window in 1st screen is brought to front.

Created attachment 134494 [details] screenshot - scaled from 3840 to 2500 for size compliance Focus follow mouse is what I have been using Since KDE 2.x and probably before... I cannot reproduce this problem currently, on Kubuntu 20.10, plasma 5.19.5
I can no longer reproduce it, either.
