The repro can be found here - http://jsfiddle.net/desandro/VQM7x/  - none of the rects should move when scrolling that container.

Note that safari "stutters" on that test case, I believe this is related but slightly different issue.  For chrome, this was solved by avoiding overflow on the repaint rects - https://bugs.webkit.org/show_bug.cgi?id=84979.  Its likely that overflow in a different place may be causing that same behavior for Safari.
