I have also noticed this tearing. 2D Responsiveness can be incredibly bad. I found out sometime ago that it could be compositing that was messing everything up. But I thought it was from the Desktop Environment point of view, that is, for example, gnome's 2 metacity trying to put some nice transitions when starting my computer (which sometimes worked, but almost always didn't). I tried using the low resource option in gconf, but that didn't help. So I switched to xfce 4.8 (Debian testing). All desktop effects are off by default. And the problem remained!
So finally after reading more stuff, I decided to disable composite and aiglx in the xserver. I put a file: /etc/X11/xorg.conf.d/composite.conf with the following: Section "Extensions" Option "Composite" "Disable" EndSection Section "ServerFlags" Option "AIGLX" "off" EndSection After booting up again, performance was instantly better. I would say this is a better solution than giving up performance using Option "EXAVSync" "True". Desktop is very responsive and videos playing without tearing (both vlc and mplayer). Sadly the xorg log still shows aiglx is enabled, even though the same log also acknowledges my configuration file and disables it early on. So far, performance has been good and no problems, but have I truly disabled compositing? or is it still lurking around refusing to be shut off?
