Hello, last update. The bug is solved in 2.6.39-rc5, but wasn't in -rc4 (kernel ppa builds). So I think it can be easily tracked down (unfortunatelly, I don't have time to do it) which change solves it.
Please, mark this bug as 'Invalid'/'Fix Released'/'Won't Fix'/whatever - I am not sure which is more appropriate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763527 Title: [natty] regression with radeon module (ATI Mobility HD 4570) causes minor display artefacts -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
