I addded a simple sphere with vertex colors (colored inside rhino, with gh c#), and the viewport flips to white after i select a surface (shade highlight on) and rotate the view.

I am aware that the drivers are ‘old’, but this is not by choice: As with many laptops there is a ‘supported’ nvidia driver that comes from the laptop manufacturer.
Updating to the newest drivers breaks a lot of things.
Workaround is to set the vertex color object to another displaymode
