If you feel it's a bug, you could submit a bug report...

I agree that the marker is not boldly visible, but with my 66 year old eyes
I don't have a huge problem seeing it, neither when it's reddish-grayish
over the pale red highlight of the line nor when very near, when it turns
solid red.  In my display, once the marker turns solid red, the pale red
highlight goes away.  It does seem a bit odd to me that the midpoint marker
is smaller than the + cursor, though.

I guess it would be nice if changing the size of the vertex crosses in

Again, maybe you should submit a bug report / feature request at the link
above...
