Unity UI Samples - 3d Menu broken in 5.3.1?

I just upgraded to 5.3.1 and downloaded the Unity UI Samples package. I loaded up the 3d Menu scene and alas the menu is not there. I think the menu is there but the visuals are not.

I noticed this disappearance with a VR app I was working on which I had built a 3d menu using the UI samples, which led me to import the UI samples into an empty project for testing

Any ideas?
