I beleive there are 2 issues here, one with Intel GPU and is solved by the CLUTTER_VBLANK trick, and the other (comment #6) with NVidia GPU (with the legacy 173.x driver, I have a GeForce FX 5500 and cannot test if the bug also exists in more recent drivers) and affects only mutter (unity is using it, right?) and thus gnome-shell.
As a starting point for investigations about the nvidia problem, it seems to be related to clutter 1.2 (if I downgrade clutter to 1.0.8, it's no longer slow). -- quadrapassel and gnome shell very slow and unusable probably a clutter issue https://bugs.launchpad.net/bugs/572465 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
