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. SOFTWARE/OS VERSIONS Windows: NA macOS: NA (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: 6.4.4 KDE Plasma Version: 6.4.4 KDE Frameworks Version: ?? Qt Version: 6 ADDITIONAL INFORMATION Has been happening for months.
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
This also affects Wayland
Created attachment 188119 [details] attachment-3455815-0.html What's the easy workaround? The tooltip prevents clicking the buttons when clipped.
