Same problem here with a Radeon HD 4770. And I just solved it, like eundas, in OpenGL plugin in the CompizConfig Settings Manager : when disabling vsync.
And trust me, the problem is solved but the vsync is not disabled. In fact it seems that this vsync option was over another one, the driver one (set in amdcccle), and the both resulting in a very slow display, even slower than a picture out of two. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/760814 Title: Compiz Very Slow and Choppy in Natty Classic -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
