Please, watch this video to understand this strange behaviour. It happended with the last Rhino update.
All my dashed single lines now are drawn flat in all my Rhino 8 drawings. Saving the file in Rhino 7 version the lines are shown correctly with the right linetype patterns.

This bug was fixed in the last few days. Hopefully you’ll see this fixed in the next WIP build which we should have available later today.
