@benpicco, To see if your problem is the problem described in this bug, try turning off the X to GL sync.
If you haven't already, install compizconfig-settings-manager. After that, start ccsm and then go to the OpenGL tab. Uncheck "X11 Sync objects". If this makes your issue go away, then you are dealing with this particular bug. That said, looking at your log snippet, I'm thinking this is an issue either in the NVRAM of your card perhaps exposed by the driver or in the driver itself. -- 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/1424013 Title: Compiz high CPU and UI freeze on NVIDIA after fix for #269904 in trusty-updates To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1424013/+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
