Sorry for the long delay. In standard Emacs usage you shouldn't ever
see half a line displayed at the top of the screen. Are you using
pixel scroll mode or something?
The only alternative I can think of is that the inertia just pushes it
over the edge to scroll one more line, but I don't think you would see
that as "flickering", just an extra scroll.
To disable inertia in Emacs do:
(setq ns-use-mwheel-momentum nil)
