Rhino 8 - Surface Edge not working properly

Hello all,
I’m facing a frustrating issue with Rhino 8. Whenever my scenes become too complex, the geometry edges behave strangely in the rendering viewport—they disappear and reappear as I zoom, rotate, or pan. I’ve tried everything I can think of, but the issue only resolves when there are fewer solids displayed at once. I have friends facing the same issue. I use Nvidia GPU. Please advice, this make it so hard to work with.

It is more likely someone will look into this if you upload a .3dm file which shows this behavior

Have you tried to change the lens length? Sometimes, it’s the reason for these weird rendering issues.
Also, check if there is some very distant object in the scene. Is your model close to the scene origin?
