Hello. I had the same problem that was driving me crazy for days but today I figure it out. At least one scenario:
If I open a Chrome window on, let's say on the second workspace, and go to youtube and let the video play in background. (not minimised!!) if I change the workspace it's freezing constantly. I'm using Ubuntu 17.04. Please let me know if you want more information about this scenario. I would be happy to help. -- 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/815996 Title: Desktop occasionally freezes/locks up when switching workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/815996/+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
