           Summary: [RV630]: a lot of artifacts appears on a screen
                    playing some videos through VDPAU

video with artifacts screen shot

Using mpv player:

mpv -vo vdpau -hwdec=vdpau file.wmv

I'm expiriencing a lot of artifacts appears on a screen during playback. Please
see screenshot in attachment.

With next options:

mpv - vo vdpau -hwdec=no file.wmv

it plays good without any distortions.

So it seems the artifacts appears only with hardware acceleration enabled.

Note that the same issue us not only with git drivers but with stable too.

Linux 4.6.2-040602-generic x86_64
