Hey, I'm having a rather specific and odd problem that may not be solvable. So I'm creating just some simple 2 dimensional triangles for diagrams for a Physics lab. Now, I've run into a problem where whenever a line (shape, single line, curved line, etc.) is made there are these almost BOLDED dots at the end. I'm unsure if these are supposed to be there, but I don't recall ever seeing them before. It could be the format I'm using, but I can't easily click on specific overlapping shapes when their bolded corners make it impossible. That, and the bolded corners look aesthetically bad. Regardless, any help or notice about this problem of mine would be greatly appreciated! I'll include a link to some screen shots of what I'm talking about.

Screen shots are weak, but I hope I got my point across.
