Created attachment 123202 [details] gap between window and content visible SUMMARY When using fractional scaling (e.g. 1.25) on Wayland one can notice a gap between the window content and the window decoration. Comparable to what we always had when enabling wobbly windows. STEPS TO REPRODUCE 1. Use Wayland 2. Use fractional scaling of 1.25 3. Use window decoration borders OBSERVED RESULT Gap between window content and window decoration (see screenshot) EXPECTED RESULT Properly rendered window ADDITIONAL INFORMATION Version ======= KWin
