Binary package hint: xserver-xorg-video-intel

Starting the KDE desktop the desktop effects are disabled. When enabled manually, all effects seem to work but after some time the desktop freezes. I can still move the cursor and change to the console.
The console is flodded with following error messages:

[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 251495 at 251463)
