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.
