Symptoms

A .NET + XNA 4.0 game (also uses SlimDX, if that's important), has a weird blur over the picture while ingame, impossible to see anything. HUD and dialogue elements are unaffected, also the blur disappears for a few seconds when you get hit (see the last picture).

Also has a video codec issue, shows a color bars screen instead of intros + missing all the music (haven't tried to transcode wma to ogg).
