What is the command name to correct the display precision

Rhino Rhino for Windows

Hi,

I see some edges of meshes and breps that should be invisible, because they are behind objects.

I know that there is some sort of command to increase display precision.

Could someone remember this command name on Rhino6?

The issue is visible in this screenshot:
