This is also easy to see in http://people.mozilla.com/~bstover/scrolling.html

I noticed it in a Fennec 7.0 nightly on Android.

We should track this for Fx7; it's a regression that breaks rendering of some pages in Fennec.

is this the same as bug 667516?

[Mark Finkle (:mfinkle) (use needinfo?)]

Still need a regression window.

Ben - can you take a look?

I think this bug must be a regression from 637852. This fixes the issue (and also removes another bug where subsequent sibling layers got the product of all of its previous sibling layers, though I doubt this ever has come up in practice).

Requesting approval-mozilla-aurora for this patch, which fixes a regression in Gecko 7 that causes many pages to render incorrectly in Fennec.
