Hi Morten -
I’m not able to reproduce this here so far.
It looks, though, like some different settings are used. What happens when you use default (unmodified) display modes?
Also, are you printing to vector or to raster, and, if so, which DPI is being used? Is that latest screenshot a copy of the final PDF or from the layout? Are you printing with the RhinoPDF engine?
