Description armoire.mountable405 2023-05-03 14:14:53 UTC

SUMMARY
Everything window-switching and focus-related goes horribly wrong when using Activities.

STEPS TO REPRODUCE
1. Open a second activity.
2. Switch to it.
3. Open a few windows.
4. Alt-tab through.

OBSERVED RESULT
Focusing one window brings the previous one to view. Dim feature dimming active window. Clicking windows falls through them to the background windows. 

EXPECTED RESULT
Normally working focus and dimming.

Same issue. Changing focus through Alt+Tab or task list does not bring the selected Window to front. launcher are also effected and opens behind other windows as soon as there is at least one window on another activity. 

But: Input focus for mouse and keyboard is on the correct window!

I've been seeing similar behavior for a long time. Oddly, Alt+tab kind of focus on the correct window, but mouse focus selects the previous window. This is the sole reason I don't use Activities, as it really renders them unusuable. Also, once the broken behavior is triggered, if I go into Settings > Window Behavior > Focus, and change the window activation policy to something else and apply it, window focusing starts working correctly (until I activate/deactivate Activities again, at least).

Do you have the "slide back" effect enabled?

So, I was able to fix this behavior in my case by removing a kde file, but unfortunately I'm not exactly sure which file it was. I think it was removing the ~/.config/kdeglobals file, but of course I could be mistaken. However, removing some configuration file fixed the issue in my case. I wish I had more information, or that I had the forethought at the time to save the old version of that file for comparison.
