test case of moving compositing layers by CSS animation
Subpixel rendering causes repainting compositing layers moved by CSS animation.
This seems the intended effect of subpixel rendering.
But, this degrades CSS animation performance.
I think WebKit needs a solution, for example disabling subpixel rendering.</pre>
