As the code currently stands, during gpu compositing, the graphics layer corresponding to a WebGL context can be asked to render its contents into a canvas backed GraphicsContext, resulting in an expensive GL readback operation that's not necessary. In the chromium code this happens when calling GraphicsContext3D::beginPaint() which was implemented for the software compositing path.
