Comment on attachment 146717 [details] Patch Looks fine. Is there any way we could adjust one of the pixel tests which uses requestAnimationFrame to verify this behavior? r=me in the meantime.

Unfortunately there's no way I know of to test this automatically example of bug clear canvas to green wait for composite at this point any read will be 0,0,0,0 but display will be green draw with count of 0 at this point composite should show cleared canvas since the draw should have forced a composite but there's no way to test, at least not with layout tests. a screen capture could test this. Put manual tests here for now. https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/manual/
