1062223 - Scrolling upwards leads to flickering/jumping around of the bottom edge

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: Toolbar, defect)

Steps to reproduce:
Go to a page which requires scrolling, then scroll down (to the bottom, or at least a few screen heights).
Now scroll back upwards.

What happens:
When scrolling upwards, Firefox discards the bottom part of the rendered page too early, leading to the bottom part of the screen being intermittently replaced by blank space (see the attached screenshot, on my actual device the blank space at the bottom appears black).
When scrolling slowly, this leads to the bottom edge of the screen jumping around, with faster scrolling it transforms into flickering.

What should have happend:
Scrolling should work normally :-)

Further infos:
FF32 is affected, FF31 and the current Nightly aren't.
My device: Samsung Galaxy S3 Mini, Android 4.1.2

I cannot reproduce this on Firefox 32 or 35 using a Samsung Galaxy S3 and a Nexus 5.
