<pre>I get occasional glitches while watching HD movies with VLC. This happens with
the newest version from git a8d1eaf6ee1fed0aeff681d33864e17cb904ddd3, and I did
not observe it when using 57c48e4973ac0dad09744eaa82315a5f023094e7. However
this might just be a coincidence and does not necessarily mean that a bug was
introduced between the two version.
Symptoms: The images freezes for a few seconds and then comes back with
artifacts similar to what it looks like when a key frame is missing.
/sys/class/drm/card0/error attached.
