I believe you because I didn't try with those dimensions ;-) The OP started by saying that the frame should be _wider_ than 80 columns, and my assertion above should have been "the frame width is not relevant". > >> It doesn't happen with nlinum-mode, probably because with nlinum-mode > >> when the left window scrolls, the margin in the right window is widened > >> too. > > > > I see this with nlinum-mode as well.

In my experiments, the margin starts at 3 columns, and stays at 3 columns.

Because Emacs scrolls the frame in the other direction.
