Looks like it may be the culprit.  Could you try and take a look at those
overlays to see what they look like?
If you just

  (pp (save-restriction (widen) (overlays-in (point-min) (point-max)))
      (get-buffer-create "*overlays*"))

and then look at the *overlays* buffer, you should be able to see the
start/end points of those overlays, so you can at least see if
they're empty.  You maybe also want to check whether some/many of them seem
to be piled up one of top of the other.

Further than that you'll have to use `overlay-properties' on some of
those overlays to get an idea of where they come from and what they're
supposed to do.
