1126795 - Black rectangles appear over parts of content while scrolling

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Stefan]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150122214805

Steps to reproduce:

Difficult to reproduce as the issue is erratic, although frequent. Go to any longish page with lots of content, like http://www.zweigmedia.com/RealWorld/integral/numint.html   and then scroll vertically quite fast using a scroll wheel.


Actual results:

Some content is temporarily replaced by black rectangles. These rectangles either vanish on their own in a second or less or, on occasion, persist until the content is scrolled out of range and then back in. 
This behavior is unique to FF 35.0.1; did not occur in earlier versions



Expected results:

No black rectangles.

Hi,

I can't reproduce this issue with Firefox Nightly 46.0a1 on Mac OS X 10.10. 
Stefan, do you still have this problem? If yes, please download the Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem.
