I suspect that by now you have a pretty good idea of what is going on but I still went ahead and made the change that you requested -- I can confirm that I can use the latest version of Compiz in trusty-updates on the machine I was having problems if I disable "X11 Sync objects". The reason for the delay is that this machine is used by three other users so I needed to find a way to make the change from the CLI so "X11 Sync objects" is disabled for all of them at login time because otherwise they couldn't even run CCSM because the GUI is frozen. For reference, I accomplished this by creating /etc/dconf/profile/user with the following contents: user-db:user system-db:system-wide Then I created /etc/dconf/db/system-wide.d/00_compiz_site_settings with these contents: [org/compiz/profiles/unity/plugins/opengl] enable-x11-sync=false and then I ran "dconf update". Anyway, is there a performance penalty by running with enable-x11-sync disabled? Just wondering if I should go back to the previous Compiz version or if it's okay to run the latest plus this workaround.
