Description Riccardo Robecchi 2025-03-17 08:26:23 UTC 
SUMMARY
I have three screens: the laptop's, a second screen that mirrors the laptop's, and a third screen which is on top of the second (both physically and in Plasma's configuration). When I activate the Overview effect, I can only select windows on the third screen; hovering on the windows does nothing, and clicking on them only dismisses the Overview effect.

STEPS TO REPRODUCE
1. In a multi-monitor setup, start the Overview effect
2. Try to click on windows on the screens

OBSERVED RESULT
On one screen, the click will yield no results.

EXPECTED RESULT
You can interact with windows the same way on all screens.

Ultimately the same issue as Bug 481222; same root cause, and fixing that will fix this.
