Re: 1920x1200 video playback performance
I found the solution to my performance problem: it is compiz. When turning compiz off, then the problem disappears. The same issue applies to KDE translucency. Any of these effect features causes the problem. I find that very disappointing though since they are really nice, and without them the desktop is very plain. Maybe anyone has a way of dealing with this so that compiz or translucency use doesn't interfere with video playback?
