Dear Maintainer,
While using the system under Wayland, I have observed the following
kernel error
related to the Intel i915 GPU driver. The error has been seen multiple
times,
but it does not cause any visual artifacts, freezes, or other
noticeable issues:
i915 0000:00:02.0: [drm] *ERROR* Atomic update failure on pipe A
