Looks KWin-related; moving.

Comment 2 Germano Massullo (Thetra) 2021-09-08 08:42:16 UTC

I am no longer experiencing this problem. I don't close the bug since I have seen Nate working on this, so he may still need this bugreport

Plasma 5.22.4
KDE Frameworks 5.85.0
Qt 5.15.2

Comment 3 Nate Graham 2021-09-08 17:29:07 UTC

I am definitely not smart enough to work on this, but it wouldn't surprise me if it got fixed, as a lot of KWin's wayland-related plumbing has been improved recently. Let's re-open if you see it again!
