> 2) It only occurs on multiscreen setups No, i have only one monitor here, and it happens here too. See Bug #890785, which was marked as a duplicate of this bug, but it is not. https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/890785
The Bug here is talking about dual-head monitors, that i don't have/use. I have an NVidia Geforce GTX 550 Ti videocard and clone mode etc. is turned of in nvidia-settings. Bug #890785 has nothing to do with this bug or dual-head mode or two monitors, it also happens on one monitor systems. > 3) It only and always occurs when the Unity plugin to Compiz is active. No, i deinstalled and removed Unity completely from my system, and the CPU usage is still high. This bug and Bug #890785 are in my opinion different bugs, they are no duplicates. The bugs should discussed independently. And #890785 shouldn't be marked as a duplicate of this bug here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/877438 Title: Unity/compiz has sluggish performance on dual-head with nvidia driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/877438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
