I got hte same issue with the official natty drivers. But even also with xorg-edgers ppa.
Current packages here: xserver-xorg-video-intel 2:2.15.0+git20110714.212fa986-0ubuntu0sarvatt~natty linux-image-3.0.0-5 I'm using gnome-shell, but happens also on unity and metacity (non accelerated). The behavior degrades with time, but restarting desktop removes most of corruptions with exception of some images that may be cached and get corrupted. With a specific xorg-edgers ppa version: xserver-xorg-video-intel 2:2.15.0+git20110605.bdb396a4-0ubuntu0sarvatt~natty and adding this configuration in xorg.conf: Section "Device" Identifier "Intel gpu" Driver "intel" Option "Shadow" "true" Option "RelaxedFencing" "false" EndSection I got almost stable behavior even with gnome-shell. Corruption would happend far later, if any. But in recent packages even this configuration doesn't help (and the old package got removed from my apt cache, so I lost my "stable" configuration). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/755029 Title: [sandybridge-m-gt2+] Screen Corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/755029/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
