--- Comment #3 from Said Abou-Hallawa <sabouhallawa at apple.com> ---
I think this is a regression of r278062.

This revision replaced the call to GraphicsContextCG::setPlatformCompositeOperation() by GraphicsContext::setCompositeOperation() in GraphicsContextCG::drawPattern(). setCompositeOperation() is platform independent and should not be called from GraphicsContextCG methods. Instead we should be calling GraphicsContextCG::setCGBlendMode(). 

Note: r280095 fixed a similar problem in drawNativeImage().
