Can you try a few of these downgrades and report back on if they are working or not?
First, kde-workspace downgrade to 4.9.0, it was updated to 4.9.2 in the same timeframe as final mesa 9.0 and was a pretty large change from a glance. https://launchpad.net/ubuntu/quantal/+source/kde-workspace/4:4.9.0-0ubuntu4 If that doesn't work, upgrade it back to kde-workspace 4.9.2, then try downgrading to each of these snapshots of mesa 9.0 and see if they are any better so we can narrow down where the problem was introduced. https://launchpad.net/ubuntu/quantal/+source/mesa/9.0~git20121004.b2048c5e-0ubuntu1 https://launchpad.net/ubuntu/quantal/+source/mesa/9.0~git20120917.7cfd42ce-0ubuntu3 https://launchpad.net/ubuntu/quantal/+source/mesa/9.0~git20120903.e1673d20.is.git20120821.c1114c61-0ubuntu1 -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1061073 Title: Desktop effects are slow and desktop corruption using mesa 9 To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/1061073/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
