Why all these black dots?

[Deserttoad]

I just downloaded this file and while it looks great, these dots are hard to deal with. Is there an option to not display them?

Screenshots are significantly better than phone pictures.

You have a tool bar to the right where you can select what appears and what doesn’t -

The black dots just mean that you have connecting lines; a white one would mean a break.
