I double-checked the workaround and it still didn't work. The photo this time shows what LightDM looks like after I run "sudo mir_demo_client_egltriangle" on another VT. The triangle looks perfectly fine and spins with smooth 60 fps, but everything else is still garbage.
I don't have the time right now to downgrade all mir-related packages, but I'll try that later. ** Attachment added: "mir_demo_client_egltriangle" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1218815/+attachment/3800782/+files/IMG_20130903_131722.jpg -- 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) To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1218815/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
