most likely, the distance to nearest surface node cannot be evaluated properly by the grassmap rendering system. The issue is probably that the distance to nearest surface uses the global distance fields which use cascading resolution away from the camera. during grassmap rendering the camera is probably either undefined or defined to be way high in the air or something like that, which causes invalid results from the clipmap lookups. It may be possible to make this work by always using the lowest resolution clipmap for grassmap baking, but the only engineer capable of working on this (DanielW) is out on vacation right now. I will bring this up when I see him next.
