I'd been experiencing this bug for a few days now. It stared after installing the proprietary NVIDIA driver. It was SUPER annoying. But I installed compiz from trusty-proposed and it plagues me no longer!
Before, this bug would show itself once every few minutes. But now, it's been about 4 hours with no sign of it! And I haven't noticed any new bugs either. Not sure what info you all need, but here's some: ryan@charles:~$ compiz --version Compiz 0.9.11.3 ryan@charles:~$ cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX x86_64 Kernel Module 340.29 Thu Jul 31 20:23:19 PDT 2014 GCC version: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) Let me know if you need any more info. And thank you so much. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/269904 Title: Screen refresh problems with nvidia cards To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/269904/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
