For instance in Fennec, the text on: http://blogs.msdn.com/b/ie/archive/2011/03/14/web-tracking-protection-minimum-standards-and-opportunities-to-innovate.aspx Is scrollable when it shouldn't be.
screen cast of the issue http://lassey.us/moving-content.webm this looks pretty bad and may lead to some potentially bad memory churn, marking as blocking

this patch fixes the problem in my local build
Comment on attachment 519720 [details] [diff] [review] Do not build layers for asynchronous scrolling if element shouldn't be scrollable I think you want the condition to be != NS_STYLE_OVERFLOW_HIDDEN as I think you want to include overflow: auto.

Pushed followup for now bogus assertion: http://hg.mozilla.org/mozilla-central/rev/821740bc1b4d
I am still seeing this in today's nightly build and local trunk builds on Android (but not on desktop Linux).

I think I've stumbled upon my first ever compiler bug! We are seeing bogus values for result that is returned from GetScrollbarStylesFromFrame. Returning the result directly inside the conditional fixes the problem for me. Can others verify?
Comment on attachment 520052 [details] [diff] [review] Followup: workaround for Android compiler bug This fixes the bug for me, in my local Android opt build.
this also fixes the problem for me
Without this patch I get a reproducible OOM crash on multiple pages. For example: 1. Open http://demos.mozilla.org 2. Pinch zoom in as far as possible on the "sliding cards" 3. Pan left and right. This results in an OOM content-process crash that also leaves the browser unable to pan until it is force-killed. The followup patch fixes this.
