    Description

      See attached example. If you make it 64 pixels or larger, it renders correctly; or if you render at a larger size and then scale back down, it's OK. It only happens when renderTarget is FramebufferObject.

      On Linux, the arc will be rendered too small, sometimes with some garbage on the sides. On OS X, the whole canvas is garbage.
