Rhino geometry breaking in shaded views

Hello lovely Rhino community,

Here is an image of a problem I have been facing working on a project the past 2-3 weeks. The geometry keeps breaking in shaded views even tho it looks really good in rendered views.

I have moved the geometry to a new clean file, made it close to the center of the file and still facing this issue. Maybe I need to play with the tolerance of the units and such to make the geometry look good ?

Hi - what is the document’s render mesh quality set to? Have you tried Smooth and slower or Custom?
If that doesn’t help, please post the 3dm file.
