Sorry, no.  Please assert first that the backsizing gets done inside the
following chunk:

      (when (and (listp quad)
                 (integerp (nth 3 quad))
                 (> (nth 3 quad) (window-total-height window)))
        (condition-case nil
            (window-resize window (- (nth 3 quad) (window-total-height window)))
          (error nil)))

Then we can try to find out who created that quad before and why.
