Pixalation of surface on rendered object

I get this pixalated effect when moving a rendered object. Do you think that it’s a bug or is it to do with my computer? This happening on a MacBook.

Hello- can you please run SystemInfo in Rhino and post the results?


We have this issue on the list as RH-77271 Rendered viewport shows colorful artifacts on Mac Rhino 8
