Surfaces start to have a gradient and disappear when zooming in slightly

I have been using rhino 6 for a couple of years now and this is the first time I have had this problem.

It seems to be happening in every display mode. I have reset every display to defaults and nothing has changed. In arctic mode the surfaces are displaying as gray and flat rather than shadowed and white. I have no idea whats happening.

EDIT: Its also happening in every rhino file I open and when I zoom in closer the surface of the object closest to me disappears.

How far from the Rhino world origin are the objects and what units are used for the model?

Its pretty much on the origin and units are in feet

Hello - can you tell us what the camera and target coordinates are (Properties panel, with no selection)

Thanks, that looks fine to me - please run the SystemInfo command in Rhino and copy/paste the results here.

Hello - it looks like your setup is running the Intel GPU as the primary.

this bit:
ATTENTION:
There is only one monitor detected, but it’s connected to the slower, integrated graphics video port.

** Recommended: Unplug the monitor and plug it into one of the video ports on this device:*
[AMD Radeon RX 5700 XT]

** Any hardware configuration or cabling changes you make will require that you restart Rhino.*

I’d also install the latest AMD driver from the AMD website.
