That seems to happen on most systems. There are times I can leave
the trackball right on the edge of a movement detection feature so
that even minute vibrations can send a large enough change signal
to the mouse electronics to cause a mouse movement. Once I had the
curiosity that the movement was not symmetrical. The cursor was hard
off to the side of the screen.
