Odd Shadow Buffer in Mac 6 WIP

See the strange shadow buffer like rectangle in Rendered view - only visible when viewing from above.

Apologies for the delay in reply, I believe this was caused by a bug fixed back in Oct. of 2019 to do with the self shadowing slider in the display mode settings but that was specifically to do with technical modes…

I don’t see this problem with sun shadows on a shadows only ground plane in the Rhino 6 for Mac Beta. Let me know if you still have an issue.
