Color Glitch

Rhino
1

I’m having this issue where in Shaded or Wireframe mode, my geometry changes colors depending on how far I zoom in / out. It has no issues retaining the same color in the other modes. In shaded if I change Transparency to “1” the colors display OK. But if it changes to 0, it will start glitching again. If I apply these changes, and change to “Custom material for all objects” it will also display the colors properly, but if I reset to default it will have the same issues again. I do not have a fix for my wireframe previewing weirdly though.

The actual colors it is supposed to be: In ghosted mode:

Make sure that there are no overlapping items. SelDup might help if there are exact copies.

I had updated Rhino and also uninstalled and reinstalled and still have the issues. Trying to get the drivers updated now.

Hi Anna -

Are you also seeing this in a new model from a factory-default template and a few boxes added? If not, please export a few of those objects from your scene and post that 3dm file here.
