Rhino 5 strangely bug

Hi dear Rhino team
I have this is problem in both different PC
Please look this video Rhino 5 strangely bug

I have latest version Rhino 5 SR9. I think this is problem with material editor.

Hi Javax- One thing I see is that your video drivers, when they show on the OpenGL page, are several years old- I’d suggest updating them but it is becoming clear from other uers’ reports that the newest Radeon drivers also do not mix well with Rhino- they also have some serious problems- so, I’ll see if we can find a source for the most recent working drivers.
