Point Cloud in Block drawn on top of Geometry

I have an issue similar to the one below. If a block contains a point cloud it will cover the geometry in the Rhino workspace when using a ray traced view port. I have numerous files with referenced blocks that all do the same thing. The solution to the previous issue only works if the point cloud is not part of a block.

Hi Chad - this should be fixed in the later service releases - what SR are you running - can you please post the output from the SystemInfo command in Rhino?

Hm, well now I am only getting black viewports in raytraced - something is busted - but a full render looks like what I expect

(later, in-house, sr however)

OK, I do see the problem now in the raytraced vp. If I tumble the view or go into BlockEdit, it sorts it out temporarily… weird, thanks for the report.
