I have a model in which, when rotated, points that should be in front of surfaces are hidden as though they are behind the surfaces…
Hi - please run the Rhino SystemInfo command and copy-paste the result here.
-wim
Even though they are hidden, they are selectable as though they are in front (which they are).

I also just noticed that the line object through the dots is also hidden.
Both due for an update 
HTH, Jakob
I assume you mean video driver…?
Not Rhino itself - your graphics cards drivers, yes

and
Thanks, checking into it.
All drivers have been updated, however the problem persists. points and lines that are in front of surfaces are being hidden by the surfaces.
