I have a computer with an nVidia video card, using proprietary drivers. I experience this issue.
I have to add that after a suspend/resume cycle my videos playback slowly if they are enlarged, but normally when there's a 1:1 relation between display pixels and video pixels, meaning that hardware accelerated video resizing isn't working properly. I hope this information may be useful to diagnose this issue. Reloading compiz fixes the issue. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/887993 Title: desktop sluggish after resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/887993/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
