Rhino 7 Mac Viewport issue?

Hi - Anyone having a line skipping issue on the most recent version of Rhino7 mac? I am on a SR candidate as of today, just updated, the symptom is still there though. The issue is, depending on viewport zoom level some lines disappear and come back as the zoom level changes. Please see attached, you can see lines go on and off. It is sporadic, I don’t find any rules here.

Probably a good idea to post the text result of the Rhino command _SystemInfo which can help in diagnosing the issue.

thanks, here you are. sysinfo.txt (10.9 KB)

Nothing similar here.
