--- Comment #1 from Zamundaaa <xaver.h...@kde.org> ---
This is a driver bug, see
https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/4363. You can work around
it by setting KWIN_DRM_OVERRIDE_SAFETY_MARGIN to 2200 (or more).

Yeah, KWin just renders one frame per refresh cycle, and every second one gets
dropped by the drm backend because of that driver bug.
