Display problem Inspector / Animation window

Hi Guys,
I have a problem with rendering in the animation view.
(Looks like an onion shell effect)

At first I thought my graphics card has a driver problem - GeForce GTX 10606GB. (It is not so)
So I uninstalled Unity and reinstalled.

Since the presentation problem has not been done, I have also installed the Unity 2017Beta to compare.
Well with the 2017 beta it works normally - for my taste somewhat too dark, but no “onion bowl” effect

Hi, all ok.
Patch 5.6.1p1 solves the Problem.
