SUMMARY


STEPS TO REPRODUCE
1. Run plasma-x11 with large oxygen buttons (not sure what other widgets cause the problem)
2. Open any application window and maximize the screen
3. Press F11 to go fullscreen and again to restore to maximized

OBSERVED RESULT
Window management buttons are half above the visible screen and titlebar

EXPECTED RESULT
Window management buttons should be fully visible.

Can confirm this on Plasma Wayland 6.5.0. I think it started with 6.3 or 6.4.
Un-maximizing Windows and then maximizing them again fixes it temporarily.

With breeze and plastik, it works fine.

I can reproduce this on Plasma built from git-master

Downgrading from major to normal since there's an easy workaround
Comment 3 TraceyC 2025-12-31 20:46:34 UTC
This also affects Wayland

What's the easy workaround? The tooltip prevents clicking the buttons when
clipped.
