Possibly tiling related?

This fixes the issue for me.

noming for fennec blocker - This shows up in any situation where the content size changes, and is very noticeable if you over-scroll.

A good example, go to touch.facebook.com, bring up the side-bar, choose a short page, like 'events' - then toggle the side-bar on, scroll down, then up, then toggle the side-bar off and scroll down - you'll see the side-bar underneath the page in the over-scroll area
