@David Horváth Maybe switch to Unity 2D for the time being. It is working very well for me. Only the spread and desktop switcher animations are a bit sluggish and with some visual corruption, but other than that performance is awesome. I'm also using an HD4200 with the latest Catalyst 11.6.
The problem in general seems to be that screen updates are very very slow, as if something is limiting the frame-rate to some 2-4fps (even with no sync to vblank options activated). One good example is inkscape. Try opening it and doing some panning. With Unity it is very very choppy. Same thing with Unity 2D or Ubuntu Classic without effects and it's completely smooth. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763005 Title: Fglrx with Compiz's "Sync to Vblank" makes Unity/Compiz plugins to crawl To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/763005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
