I've included a fiddle that explains what happens - Basically, if a parent of an element being animated has -webkit-transform-style: preserver-3D, or webkit-transform, and that element is being animated outside the boundaries of the div into the boundaries, then it causes the whole parent div to shake violently. See the fiddle for an example. I'm new to this whole bug submission thing... lemme know if I did anything wrong or need to update something. Thanks.

This is a tiled layer flicker. It's slightly better after http://trac.webkit.org/changeset/131940, but there's now a jiggle at the bottom edge.
