Created attachment 186117 [details] Example of the artifact. SUMMARY Using an xcursor pack and monitor scaling 150 %, the cursors gets a vertical black line in the top left corner of the cursor image. The xcursor pack I use contains images of multiple sizes (16-24-32-40-48-...). The issue appeared after upgrading to kde plasma 6.5 and was not present before. STEPS TO REPRODUCE 1. Open Kate. 2. Make the window maximized, then windowed. 3. Hover over text when the window is windowed or maximized. The artifact can also appear in any other application. I see it happen in firefox. It does NOT seem to happen when windows are on a 100% scaled monitor. Other way of reproducing the artifact : 1. Have a window open on a 100% scaled monitor. 2. Drag the window to a 150% scaled monitor. 3. Hover over the screen boundaries as if you wanted to resize the window. OBSERVED RESULT The cursor will have what seems to be a 1 pixel wide half cursor size height black line in the top left corner of the cursor image. EXPECTED RESULT No black line artifact.

After digging through the commits made to kwin, seems like this commit may have already resolved the issue : https://invent.kde.org/plasma/kwin/-/commit/705ca2b3e27fbedf81ee308f9b7cf0f414ced76b which aimed to fix the bug report in this report : https://bugs.kde.org/show_bug.cgi?id=510555 From the picture posted in the bug report linked, it seems to be the same kind of issue I have.
