When I play a movie with Mplayer my screen goes completely black for 2 seconds before I can see the movie, same thing happens when I exit Mplayer. This doesn't happen wit Totem movie player and I think it has something to do with Mplayer enabling/disabling the screen saver.
It's not a big problem, but is kind of annoying. Anyone else seeing this behavior? This is with RadeonHD from git on a RS780.
Other than that the driver works fine.
