I have now tested the beta driver for a while. In Unity: The problem is partly fixed. There is still problems with the window management: * Still no smooth window movements * The window animations, e.g. when windows are created or minimized, are still slow.
However, the performance problems with the dash and the launcher are now gone. The dash was very fast even at the time when compiz struggled with window animations. In Gnome Shell: It seems to work OK. So I guess there were two problems. One that is fixed by the driver and another one still present that seems to be related to compiz. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067432 Title: High CPU usage and lag To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1067432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
