R-GUI Editor Window Offset

When loading R-GUI I'm getting this weird offset where the editor
window is scrolled to the right slightly (~2 characters worth).

Here is an image showing what's going on:

Annoying, but not a showstopper.
I just tried it with [R.app GUI 1.72 (7841) x86_64-apple-darwin17.0]
and it does it as well. I assume this is a editor/GUI issue and not R
itself.

Thanks,
