Rhino Interface on windows 10

I installed rhino 5 64bit on windows 10.
The computer is a brand new MacBookPro 15’ with double partition mac/win
Rhino interface behaves strangely since the icon change size when I’m moving the mouse on them and gets smaller or larger overlapping each other.
Is it an incompatibility with graphic card? Would it be better to reinstall windows 7 (as I used before without any problem)? Any suggestion?

Which service release of Rhino 5 did you install?

No one yet. I’ll check for any available. Thank you
