--- Comment #7 from Jason W. Bacon <jwb@freebsd.org> ---
(In reply to Vladimir Kondratyev from comment #6)

By jumpy I mean I move my fingers a considerable distance without any respo=
nse
and then the window suddenly scrolls 1/4 to 1/2 its height.

I recall reading a post by another user about this issue somewhere.  He sta=
ted
that the wsp driver does much better than atp.  Like I said, though, it's n=
ot a
big issue in my view.  I'd focus our time on more serious bugs that affect
basic functionality before going after this one.
