As far as i know you have to "zoom in" to get rid of the artifacts at
the borders, as Bouke already mentioned. The filter documentation[1]
actually mentions an option "edge" which sounds like what you want to
change. Try different values for that. Maybe "original" is what you're
looking for.

As an alternative to the deshake filter you can use vid.stab[2][3] which
is intregated with two filters in ffmpeg (if compiled in the right way).
It only supports 2-pass-encoding in ffmpeg. You also get some "wobble"
artifacts at the border, but it isn't that bad most often. You might
still want to crop a bit at the edges.
