SUMMARY The mouse cursor looks completely broken when its size is set to any value above 48~64 pixels, this can also occur with smaller cursor sizes but larger screen scaling. And when apps request to set the cursor to a large bitmap. Reproducible with the default Breeze and 3rd party cursor themes. STEPS TO REPRODUCE 1. System Settings > Colors and themes > Cursors. 2. Set "size" to e.g. 72 3. Apply settings OBSERVED RESULT The cursor appears broken and somewhat stripey or glitchy, may also flash rapidly if the cursor is animated. EXPECTED RESULT Maybe switch to software cursor? SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 GPU: AMD Radeon HD 7560D (TeraScale 3 "Trinity" IGP), `radeon` driver
Can you dump output of "drm_info" when the cursor is in this broken mode.
