Created attachment 143714 [details] system settings window state buttons improper positioning System Settings Window titlebar state button elements don't follow the resizing upon snapping to right side of the screen. STEPS TO REPRODUCE 1. Be on Wayland session; 2. Open System Settings; 3. Snap the window to right side screen corner; OBSERVED RESULT Window state buttons cut off/improperly positioned in the titlebar EXPECTED RESULT Window state buttons follow proper window resizing SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux (available in About System) KDE Plasma Version: 5.23.3 KDE Frameworks Version: 5.88.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Only happening to system settings window as far as has been observed. Only snapping event creates bug.
Can confirm, Wayland only. What seems to be happening is that KWin is positioning part of the window out of view to honor the user's tiling preference, instead of scaling down the window below its minimum size, as it does on X11. Scaling below the window's minimum size as the *potential* to beak the window, but positioning is partly off screen guarantees it, so I think this behavior is a regression compares to what it does on X11.
The minimum size has been removed in Qt 6
The minimum size check*
