Wrong color scheme in preview

For some reason now I have this kind of representation of surfaces. Even though, all color templates are set to default, i believe. The strange part is that surfaces seem to be turned inside out, because when I go “inside” the sphere, colors there are as they are supposed to be. Any suggestions on what could be the problem? thank you

Can you post the data from the Rhino SystemInfo command?

Thank you for your answer!

Exscuse me, I’m afraid i dont have that info any more since I have solved it by a complete unistall with following reinstallation of Rhino

Glad that fixed it.

Same here, and re instal did not solve the thing.

here the Rhino SystemInfo command:
