GPU display problem in rhino 6 & 7

[Hoàng_Trọng_Bằng]

Please help me, how to fix this problem, i set up rhino and window over and over again, but it still be the same! I checked and find out it was because the Gpu driver doesnt match with rhino, even version 6 or 7 still be the same display like that. Can anyone tell me how to fix this without replacing my VGA???
Thanks!!

Turn off GPU Tessellation in Rhino’s OpenGL options. You most likely have the latest GPU driver for an AMD card which has been having this issue with Rhino.
