Monochrome DisplayMode does not respect the GroundPlane when Manual is selected.
Other DisplayModes has similar problems with correctly casting shadows on a GroundPlane, when it is not set to “Automatic”. A typical geometry could be a house created at Z=0 with a staircase leading to a basement (Z= -3m). When setting the GroundPlane Height to Manual Z=0 the shadows should be cast from the corners of the house. The house should not look like it is hovering over the ground. I recall this was also an issue in Rhino 8 at lauchtime when the Monochrome DisplayMode was new.
