Just upgraded my xvba-video installation from 0.7.8 version to the yesterday released 0.8.0-1.
Unfortunately there are white artefacts on the screen, when playing movies. My fglrx version is 11.6 also from yesterday.
Downgrading to version 0.7.8 fixes the problem. I could not find a bugtracker for xvba-video, so I am posting this here.
Does anybody have the same issue and got it solved?
