Weird outlines / graphics

Hello there,

I have some really weird outline displays, antialiasing set to x8 and GPU Tessalation is on.
Really clueless. (Attached Rendered, Shaded and a Make2D to prove geometry is correct.

Probably better to share the 3dm file with this problem.

Also, it is a good idea to ensure you have a valid license and that you don’t use a cracked copy of Rhino, but rather the latest service release (37 instead of 1), which has years worth of fixes and definitely doesn’t contain potential malware.
