Comment 5 for bug 998285

This also occurs in Unity on 12.10, but is much more apparent on my older (and slower) laptop (Dell Latitude e5510); to the point where the default alt-tab implementation is frustrating to use. On my new Lenovo x230, it is much less of a problem.

Sparhawk's ccsm work-around fixes it on 12.10 for me as well.
