No, they're not. Stipples are not designed for displaying lines or bars
after all, just repeating patterns that produce something of a dithering
effect.

I use indent-bars mode https://github.com/jdtsmith/indent-bars to a great extend. Indent bars-mode uses stipples to render straight lines for ... indent-bars.

This package manages to display straight lines irrespective of operating system screen scale value or Emacs scale-mode value other than 0.

As long as indent-bars mode doesn't use other drawing primitives than what (display-fill-column-indicator-mode) is using, I think the stipple behaviour of (display-fill-column-indicator-mode) contains a bug.
