User Agent: Mozilla/5.0 (Windows NT 6.1; rv:16.0) Gecko/16.0 Firefox/16.0a1 Build ID: 20120613030535 Steps to reproduce: Visit: http://ie.microsoft.com/testdrive/Performance/Chalkboard Actual results: The demo is visible slower in Firefox than in Internet Explorer. Expected results: The image width and height are animated to extremely large values and then absolutely positioned. To speed up rendering, clip the image to (just larger than or exactly) the displayable area before scaling via GPU.
