Description boski_cinek 2021-10-01 16:02:01 UTC 
SUMMARY
Enabling action on screen corner (using Screen Edge module in Configure Window Manager) hijacks corner pixel and thus violates Fitt's law of corners. I have kickoff widget/button in top-left corner and Present Windows action configured for same corner. It worked as expected in 5.22 but it doesn't anymore in 5.23 beta.

STEPS TO REPRODUCE
1. set panel/widget in top-left corner
2. move cursor to top-left corner and click -> widget is activated as expected
3. configure some Screen Edge action for this corner
4. move cursor to top-left corner and click -> nothing happens

Unfortunately this is not possible to resolve on X11 for technical reasons. It already works as you expect in the Plasma Wayland session, thankfully.

Marking as a duplicate of Bug 387775 because it's the same root cause (and the same unfixable thing on X11 which already works on Wayland)
