http://trac.webkit.org/changeset/82969/trunk/Source/WebCore/rendering/RenderBoxModelObject.cpp turned on a new fast path for rendering rounded corners.  This broke a number of tests:

 ideo-zoom-controls.html,svg/custom/svg-fonts-in-html.html

It essentially ends up rendering the background color as black instead of the correct color.

This bug doesn't occur on Mac, just Windows and Linux, so seems likely a Skia bug.  If I use fillRect instead fillRoundedRect, the color is right (even if the dimensions are wrong).  So, it seems like a fillRoundedRect problem.

I'm going to #ifdef it out temporarily until this can get addressed.
