I just tried the latest master (make bootstrap).
I am still able to reproduce the original steps, although not every time
I run M-x eval-buffer.

(progn
  (require 'pixel-scroll)
  (pixel-scroll-precision-interpolate
   (* -1 (line-pixel-height)
      (max 0 (- (count-screen-lines (window-start) (point)) 2)))

^^^ changing 2 to 3,4,5 or resizing frame changes the scrolling
behavior. Sometimes, the recentering does leave the point on top, but
the point moves down a few lines. Sometimes, recentering does not happen
as in the original report. Sometimes, the recentering works.
