Does anyone know why the clipping plane has such issues?

Hi Sherry,
first of all I would try to upgrade the video drivers (they are from november 2019).
After that I would check how far is the model from the Cplane Origin (If you are too far, visualization can have some problems).

Hi Lucio,

Let me try to update the video driver. I have tested the origin it is not the cause.
FYI My coworkers with MacBook Pro 2020 (not the M1) with windows bootcamp have exact the same issue…
Also FYI same file in Rhino 7 the issue is fixed…

Can you attach a portion of the file where you see the problem? (probably there are some surfaces that need to be fixed)
