Very very likely simply a driver bug. A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/7290 Git commit 0b5dcb79fd876441c71e8807f28f4dd5af76b3dd by Vlad Zahorodnii, on behalf of Xaver Hugl.

Pushed by vladz into branch 'master'. backends/drm: add KWIN_DRM_FORCE_SCALING_MODE env var to force a scaling mode M +22 -1 src/backends/drm/drm_pipeline.cpp https://invent.kde.org/plasma/kwin/-/commit/0b5dcb79fd876441c71e8807f28f4dd5af76b3dd A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/7321 Quick update, I installed the kernel-longterm package provided by my distro (tumbleweed) and the issue disappeared - just to confirm that this is indeed kernel/driver related. Now I'm on 6.12.18 and it's working fine.
