Description

Created attachment 8588228 [details]
SVG graphic illustrating the problem - rectangles of shades of gray.

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0
Build ID: 20150217104802

Steps to reproduce:

Display an SVG image which has filled gray rectangles that abutt - the edge of one fully meets up to the edge of the other.


Actual results:

There appears to be a visible gap between the two rectangles that should not be there.


Expected results:

The transition from one rectangle's color to the next rectangles color should be smooth, without a non-fill color transition effect/gap being visible.

I've managed to reproduce this issue on the latest release(42.0) and latest Nightly(46.0a1). Still, I get a pop-up with the following message(see attachment) each time I open or refresh the page. This occurs on Chrome and IE as well.

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Chrome behaves the same as Firefox, only IE works correctly.
Considering this, I will mark this issue as New and assign the appropriate component.
If anyone considers that the component is not the right one, please change it to a more appropriate one.
