I also have the same issue with Nvidia 8600 gt on a AMD X2 system. I tried both nouveau open source drivers and proprietary drivers. On classic ubuntu desktop everything is OK. On unity desktop, lag is unbearable. Although I have to note that open source nouveau drivers improved things a little bit; but still it is not enjoyable to use ubuntu anymore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774414 Title: Window movement in Unity jerky -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
