About 5 minutes after posting this I found a kind of workaround that seems to improve things a lot:
in ccsm (compizconfig-settings-manager) in the composite plugin, deactivate auto detection and set the refresh to something like 60. restart compiz by doing compiz --replace --- also in nvidia-settings, check if the powermode is set to performance (in the powermizer entry of the menu to the left) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/764330 Title: Move window annoying slow with compiz -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
