Shaded view gone mad

Hello guys,

Since yesterday my shaded view has gone weird. It seems to become a mix between the normal shaded view and the wireframe. How could I make it as it used to be? I upload two images, one shaded and one rendered. I am running Rhino 6.

Thank you in advance,


I have just discovered something very interesting. The wireframe of the objects does not always fit with the actual shade. Look at the picture to understand what I mean. Maybe this will be helpful for your advices.

I suspect your model is too far from the 0,0 coordinate origin.
To fix this, turn on everything, select it, move it closer to 0,0.
Run ClearAllMeshes, then co back to a shaded stye display.
