SUMMARY When using the wayland session with xwayland fullscreen windows, it can happen that there is one pixel at the bottom of the window where the desktop/hidden taskbar shows through. In addition, when spawning a xwayland program, it can happen that the title bar and window itself are separated by one pixel that shows desktop/below windows through. Even more occasionally, it can happen that the right side of a window has a 1 pixel border where the desktop can be seen through STEPS TO REPRODUCE 1. Open a minimum of two application that uses xwayland 2. Fullscreen both applications 3. Minimize the applications 4. Restore the applictions by clicking on them in the taskbar or alt-tabbing to them OBSERVED RESULT Observe the 1 pixel border at the bottom of the screen (and/or right side of a window) that shows the taskbar through it. EXPECTED RESULT The window is fullscreen with no 1 pixel border. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.27.3 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Video that shows the 1 pixel border: https://www.mediafire.com/file/oznsz7s4ccenw3t/PXL_20230328_214452939.mp4/file
When you say "fullscreen" do you mean "maximized?" Because these are actually different states. Does it happen with both states, or only one? What scale factors are you using?
I mean maximized. there is no issue with fullscreen. the problem is only apparent on non-integer scaling factors (100%, 200%, etc work fine) with maximized windows. for example, I use 150% scaling factor on a native 3840x2160 monitor where the issue is present.

My apologies for submitting a duplicate report. I did search for reports but could not find anything open. I must have been using the wrong keywords at the time.
Don't worry about it. :)
