We know that benchmark and game performance in Compiz/Unity is less than

Thomas: We plan to backport the changes to Unity 5.x for precise in the
coming weeks, after no further related issues are found by Unity 6.0
users.
This means the change will definitely hit precise by 12.04.2, possibly
in time for 12.04.1. However I'll publish a PPA for precise testing

Thanks Daniel, that's very helpful. We would love to test it once you have
the backported patches ready. Is it planned to backport all the bugfixes
mentioned in the changelog, or only some of them? (If only some, is there a

That's right. Unredirect fullscreen windows should fix performance for

I have found that unredirecting fullscreen windows does help in many of
