I still have this problem. I also enabled saucy-proposed, but no change. Accoring to lshw I have the following chip "Mobility Radeon HD 4225/4250"
I have xserver-xorg-xmir, xserver-xorg-radeon, xserver-xorg-ati and unity-system-compositor installed. Without USC everything looks fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1218815 Title: [radeon] Graphic glitches and screen corruption (vertical lines) on XMir surfaces only To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1218815/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
