Various bug (Rhino 6 wip - 25/07/2017)

Rhino Options - shaded mode - (uses advanced GPU-based lighting) - does not make any changes by turning it on or off.

Shades clipping plan: if active “solid color” does not change anything.

(Updated GeForce gtx 960 video driver)

Can you please post small example files and any instructions needed to duplicate the problems?
