Go to gmail.com
Open an email which has a lot of replies. Click on the button that will "expand all" the emails
Scroll on the page

AR: Black rectangles appear on the page. If you pinch-zoom, the black rectangles will also move.

Regression range is : https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=f3fe6cc42791ae3b17782b9d30f3bc4222de9493&tochange=07613976379f96a9416021b138ba21870fe2065d

I can reproduce this as well. It is especially noticeable for me with a theme other than the default.
