Subject: bug#70386: 30.0.50; (recenter 0 t) does not put point on top of the window
Date: Sun, 14 Apr 2024 16:33:48 +0000	[thread overview]
Message-ID: <87v84jrjir.fsf@localhost> (raw)

Consider the following reproducer:

1. emacs -Q
2. Insert the following into scratch buffer and put point at "recenter"

(progn
  (require 'pixel-scroll)
  (pixel-scroll-precision-interpolate
   (* -1 (line-pixel-height)
      (max 0 (- (count-screen-lines (window-start) (point)) 2)))
   nil 1)
  ;; Call original recenter for final adjustment.
  (recenter 0 t))

3. M-x eval-buffer
4. Observe that scroll is not set to line 0, despite calling `recenter'

Changing (recenter 0 t) to (recenter 1 t) makes scrolling work as
expected.

This is on the latest master. I started seeing it only today, after
pulling the latest main.
