On my GTA01, jitter is fairly limited to bouncing back and forth between
adjacent pixel values.  It's easy to see this by SSH-ing in and running

     DISPLAY=:0 xev

and watching the values oscillate as you hold a stylus as still as possible on
the touchscreen.

This jitter doesn't really affect scrolling or drawing (using xournal, for
example) in my case, but it DOES cause the on-screen keyboard, which should
repeat indefinitely if you hold a key down, to STOP repeating after a short
unpredictable interval.
