Yes, linum-mode, and yes, it is easily reproducible.

There's no invisible text anywhere in sight in linum.el, AFAICT.  It
works by creating overlays with before-string properties that are
displayed in the left margin area.  Before-strings in the margins is
something I never tried before under bidi-display-reordering, so it's
not a surprise it has problems.

However, since I'm working on reordering strings, which will directly
affect this use case (and also holds off code freeze), I'm putting
this on hold until that job is done.

If you mean invisible text, it's bug #7616.
