To reproduce the issue do the following in both Rhino 7 and Rhino WIP.
** Note : Both Version have Rhino Render as the default engine**
1- Create a box
2- Switch to Arctic mode (with the default ambient occlusion)
3- Switch camera to use Two-point perspective.
you can see that Rhino WIP shows unexpected shading at the Horizon, while Rhino 7 Renders things nicely.
