It seems this problems still occurs in 9.10. I had the same problem in a fresh install of version 9.10 with intel 815 graphics.
My workaround was to create a xorg.conf with Section "Device" Identifier "Configured Video Device" Option "NoAccel" "true" EndSection The option with DRI didn't work. -- [i815] graphics corruption while moving mouse / opening menus (UXA bug) https://bugs.launchpad.net/bugs/373757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
