Comment 5 for bug 1660560

The modern canvas (OpenGL) does support changing the size of the dots. We don't use that yet in eeschema, but it's coming in 6.0.

Since it will solve the problem, it's not likely anyone will expend the effort to fix it in the Legacy canvas.

The ratsnest problem is a different issue as we don't (at present) have a way to set its width. We're tracking that here: https://bugs.launchpad.net/kicad/+bug/1740156
