Description Daniel Michalik 2014-10-24 11:56:07 UTC
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.
