The fringe bitmaps have fixed width specified in pixels.  I understand
you are saying that the number of pixels is correct, but its visual
appearance leaves a lot to be desired, is that right?  If so, you can
customize your fringes using this:

  (setq fringe-mode '(16 . 16))

(replace 16 with a number that is to your liking, I'm just guessing
there).

We could also apply the scaling automatically, patches welcome.
