Colour glitches in Technical Display (Rhino 7)

Custom Technical display setup - visible and hidden lines colours are set to object colours. Hidden lines are switching from objects colours to red and blue when zooming out. Same issue is visible in the exported raster files/pdfs.

eg sockets are black, If hidden, color turns to red

and changed to red - blue when zooming out

zoomed pdf looks like this:

and modified technical drawing settings:

Hello- please run the SystemInfo command in Rhino and copy/paste the results here.

Hm - it looks like objects are changing between hidden & not hidden, depending on the view.
