PBR specular/glossiness shader displastripes in specular lighting in the 3d view

I am testing the PBR specular/glossiness shader and the glossiness doesn't behave normally in the 3D view.
See screenshots attached.
BTW, is there a better place to do bug reports ?
Thanks

That happens when you have a Normal output in your graph with nothing connected to it, which makes your material have (0,0,0,0) for normals. Either remove the Normal output when you are not using it, or connect a Normal Map node to its input.
