Sorry for the Reply All, it's my first time mailing over here.

I tested it on different computers and it always happens.

These are the step to reproduce it:

   1. Open emacs with emacs -q
   2. Open an empty buffer
   3. M-x display-line-numbers-mode
   4. Insert 95 lines (C-u 95 RET)

You should see that there's an extra space on the left of the line numbers,
and
when you scroll up until line 90 or 85 (I think it depends on the window
size)
it disappears. If you scroll down again to the bottom, the buffer is again
shifted to the right.
