Which avoidance setting do you use?  I tried animate, but the behavior
is not as frustrating as you say.

The problem with mouse-avoidance-mode is that it's a global minor mode,
so disabling it only for doc-view buffers doesn't work.  I could
deactivate it temporally while slicing with the mouse, but that doesn't
help much and works only around the real problem:

  mouse-avoidance-mode makes no sense and is irritating in buffers where
  point isn't visible like image-mode or doc-view.
