http://askubuntu.com – Im having tearing occur at the top 5% of the screen with an intel onboard graphics when playing HD video during motion. I'm using mythbuntu 12.04 with updated kernel and updated intel graphics driver packages. I've tried using Options "TripleBuffer" "True" in xorg conf with no success. I've also turned on the compiz workarounds suggested here https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/755841 with no success This is the xvinfo output: X-Video Extension version 2.2 screen #0 Adaptor #0: "Intel(R) Textured Video" number of ports: 16 port base: 88 operations supported (HowTos)
