Clipping Plane - Serengeti

I’m working with a fairly large file, combination of surfaces and some mesh. When I use the clipping plane, the viewport it is initiated in is fine, but the other viewports have a degredation in image quality - as if the lines are clipped but not on the clipping plane. As if the image is outside the bounds of the viewport, if that makes sense. This is evident in the top view and a secondary perspective view. NOT in the front or side views.
When I delete the clipping plane the image is degraded on all viewports. If I save, turn off rhino, then restart all is fine…but it is waste of time…

Hi Thomas - I guess this is handled, for now, on the tech support conversation with JB.
