User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_2) AppleWebKit/537.74.9 (KHTML, like Gecko) Version/7.0.2 Safari/537.74.9

Steps to reproduce:

1. Use a HTML element with a style which uses background property with SVG image
2. Apply a CSS transform with scale and rotate to it (or container element)

This doesn't happened then the <object> is being used.

Test case: http://jsfiddle.net/nGdnM/1/


Actual results:

The presentation of the SVG becomes pixelated. The same SVG in the <object> tag  remains sharp after applying the same CSS transformation.


Expected results:

SVG when used as background image should have sharp edges regardless of scale/rotate transformation.

I would say it's the same in Chrome

It's definitly not the same in Chrome, I just checked OS X as well as Windows 7 (Chrome left, Firefox on the right):

Note that I increased the scale factor to 3.5 for better visibility on http://jsfiddle.net/nGdnM/2/

This looks like a regression from ff26 to ff27.

Here is a screenshot from the test case with ff26, which looks much better as it is not pixelated at all:

I have a different regression window for http://jsfiddle.net/nGdnM/2/ . Firefox27.0.1 render well.
