User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8) AppleWebKit/536.25 (KHTML, like Gecko) Version/6.0 Safari/536.25 Steps to reproduce: I created a mask with maskUnits userSpaceOnUse. The element that takes a mask has a transform. Actual results: This transform of the element gets applied to the mask as well. Expected results: The coordinate space of the mask is independent of the coordinate space of the rect. The mask should not be affected by the transformation of the element.

Seems to work for me on 14 and Trunk on Vista - displays a green square the same as Opera. What are you testing on and could you attach a screenshot please?

This is what it shows for me on OS X Trunk (64Bit Mountain Lion) Toggling svg.display-lists.painting.enabled to false causes it to pain properly.

It looks the same on Mac Mountain Lion with Firefox trunk for me. Half of the square is red, the other half green.
