I've found a rather easy workaround. I simply had to disable the following option in the Device section of my /etc/X11/xorg.conf (see the attached file) so that vline doesn't wait for non-pageflipped swap buffers:
Option "SwapbuffersWait" "False" Remeber to restart the xserver afterwards (e.g. log in and log out) and moving windows shouldn't be slow any more. I can't see any regressions after doing this. Note: this works with the radeon driver but should also work with intel. I'm not sure how to do the same with proprietary drivers. ** Attachment added: "xorg.conf" https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/770160/+attachment/2189374/+files/xorg.conf -- 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/770160 Title: windows start to move slow after using compiz for some hours To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/770160/+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
