Same here on Ubuntu 14.04.1 (AMD64) running Compiz 0.9.11.3 & using the nvidia-340 drivers (from xorg-edgers) for my GTX 750Ti - definitely been a recent update that caused this, I wasn't having issue prior to the recent kernel upgrade that I ran ~3-4 days ago.
As a side-note about that upgrade, I had to run it as sudo apt-get dist- upgrade. That might be the root of these evils, perhaps the kernel upgrade broke NVIDIA's drivers a bit? -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in 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 _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
