I can reproduce this. Doing C-l fixes it, and I can't reproduce after
that until I delete and resplit the window. My terminal is urxvt.
I can't reproduce in 24.3.
I notice that the `linum' face is rendered identically to the default
face in 24.4 and up. Could be related.
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.
