Xorg.0.log

With HW acceleration enabled on the r600 driver using gstreamer gst-vaapi the
screen flickers when the uvd changes its power state. This happens when you
play a video on firefox (youtube, vimeo vine etc.) or with vlc. It flickers
upon starting/ stopping and then a few more times. The monitor is connected
with DP in case it matters.
