Rhino 6: shaded viewport wired

[Jarek]

perhaps this helps to explain:

"Penguin display" RH6

Are you by chance holding down the TAB key when rotating your view? There is a little backdoor Easter egg in V6 atm that if you hold down the TAB key while manipulating the view, the NPR shading algorithm is used…but releasing the TAB and jogging the view should go back to standard shading… I’ll take it out in the next service release if it’s becoming an issue…
