I'm having the same problem, my lspci says my VGA is an Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller.
I just installed FirewallBuilder, and I am experiencing similar glitches in the interface (see screenshot), so maybe it's related, and maybe this problem has nothing to do with Blender. Maybe. ** Attachment added: "Screenshot-Firewall Builder.png" http://launchpadlibrarian.net/27512782/Screenshot-Firewall%20Builder.png -- [i965] graphical glitches with Blender/OpenGL unless DRI disabled https://bugs.launchpad.net/bugs/365776 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
