User Agent: Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0
Build ID: 20110615151330

Steps to reproduce:

http://jsbin.com/iwopir

Check this sample page. Root element have gradient background CSS. And gradient stops painting after approx 32735px. If I minimize the height of child element to 32700px then it works great. But increasing height ruins everything. There may be some problem due to integer overflow.


Actual results:

Gradient is not applied properly after 32700px


Expected results:

It should be applied until the end of the element. You can check it in Chrome.

> Regression range

Fx 3.6 behaves different but not correct (starts repeating the gradient after the magic amount of pixel).

Fixed in beta 8 now with bug 1011166.

(I thin the story here was something like this: Was a dup of bug 677174 and fixed by that but regressed in a different way due bug 1011166)
