I was working on another thread and stumbled on anew way of seeing these bugs in active detail views:
Some of the video might be slightly misleading as I noticed the grid was on, but some reason the grid settings are much different in an active detail view rather than the normal Rhino viewport:
Really weird inconsistent GUI settings … 
How do I get the active detail view to embody the same characteristics as the normal viewport …
Maybe the active detail view uses some generic cplane idk
