Thats interesting, mine looks like this on a 2013 Macbook pro retina (Nvidia) on the tip of cinder master.

Perhaps your graphics card doesnt like one of the shading passes (are you on one of the newer macbooks with AMD cards?) Click on the ‘debug view’ checkbox and you might be able to see a problem (it should look like below). If thats fine then it could be the compositing shader.
