Wow, this thread has been sitting here for a week and I get only one "me too". What happens to other people with Nvidia cards? Have you experienced no problem, solved the problem, or given up? If there is any workaround please share.I have installed emerald as someone advised but still no change.
Now the Compiz version is 0.99~daily13.03.29 Ubuntu1 and the issue has not improved. This has been a problem since Precise's release and it says on the lauchpad thread that I linked to in my first post that a fix has been released but still no luck. The launchpad thread has not seen any activity for a while, so I am going to file a new bug later.
Raring is fast and responsive except for this bug which is almost a show stopper for me.
