I've the same problem. In addition the right border (and only the right one) is transparent on any screen scale !=100%, !=200% and so on. Sometimes the transparent border also flickers until I move the window.
It came up somewhere in between 5.23-5.24.
To visualize I set window border to "Large" and also enabled "Shadow". This monitor is scaled to 115%. When I scale to 100%/200% the right border is fine. See attachmnent

Transparent right window border when scaled to any size not 100%
I can reproduce, - set borders to normals - set scaling to 125% the right border is not rendered, at 150% it's rendered Git commit c49620658f24dde055c053cfa1aac6b22997b0d0 by Vlad Zahorodnii, on behalf of David Edmundson. Committed on 08/07/2022 at 12:34. Pushed by vladz into branch 'master'. Create large enough atlas texture for decorations When we render individual component of a decoration into an atlas we ceil the positions for the individual component parts so they don't risk overlapping. See SceneOpenGLDecorationRenderer::render This isn't done when we set the overall texture height. This can cause the bottommost part of the atlas (the right edge) to go out of view.

Created attachment 148798 [details] Image of display settings, where the border around the image does not render on the right side SUMMARY When the display scaling is 100%, the window borders render as expected, beautifully. However, I crank the scaling up to 110% because I am a bit hard of sight, and the right border on the window leaves the building. Please see the attached image for more information. I took a screenshot of my window with the scaling settings, in the screenshot you can see the border stops at the right side of the window STEPS TO REPRODUCE 1. Change scaling to >100% 2. Enable Window Borders OBSERVED RESULT No rendered window border on the right side of the window frame EXPECTED RESULT Complete border around the frame.

Kernel 5.17.4 (available in About System) KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION I use two monitors. When I move the window from the 110% scaled monitor to a 100% scaled monitor, the right border begins to render again on the window immediately.
