according to sources, G965 does not provide video overlay. It provides
textured video only. (at least it does not setup adaptor for video overlay for
G965). Anyway, using xvinfo, can you see attributes like saturation or gamma
for any adaptor? If not, you are only using textured video thus you cannot
expect tearless video.
