------- Additional Comments from Nat Duca <nduca at chromium.org>
This bug occurs on WebGL content because it initializes the shared graphics
context before the compositor. The compositor then turns on in WebViewImpl but
forgets to tell the RenderWidget that compositor is turned on. RenderWidget
proceeds to draw as if the page was software rendered.
