If a non-accelerated canvas2D call is made (e.g., strokeRect) followed by a call to drawImage() of that canvas to another canvas context, the results will be incorrect (the stroke is not shown). This can be seen on sites such as http://canvasrider.com/tracks/695376, although there doesn't seem to be a layout test that covers it.
