I've now experienced the same problem with Gnome shell, although there it's slightly different as even moving windows doesn't cause the screen to refresh, I have to open the activities view and close it again to see that a window has updated or even moved. It did work fine for a long time before that problem though. So it appears that this bug is probably with the Nvidia drivers. However, I didn't have any graphical issues with Kubuntu 11.10 on the same machine with the same driver.
I've tried upgrading to the Nvidia 280.13-0ubuntu6 drivers from the ubuntu-x-swat ppa but without any improvement. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907709 Title: Windows fail to refresh unless moved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/907709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
