It is definitely related to trying to scroll while the last line is not
fully drawn. As Emacs resizes the frame at startup (and perhaps other
frame's creation) time to display full lines, the bug doesn't appear
unless you do something to draw partially visible lines. An easy way is
to put a header line whose contents is of a different height that the
lines in the buffer.

Yes.
