Evaluate the form below, the deleted image remains displayed partially
in the window.
In my environment, (window-pixel-height)=>560, (frame-char-height)=>16.
The attached image is the screenshot of the result.
(let* ((buf (generate-new-buffer "tmp"))
(w 512)
(h 512)
(pbm (concat (format "P4\n%d %d\n" w h)
(make-string (* (/ w 8) h) ?U))))
(switch-to-buffer buf)
(dotimes (i 50)
(insert-char ?X i)
(insert ?\n))
(goto-char (point-min))
(redisplay t)
(insert-image (create-image pbm 'pbm t :scale 1))
(redisplay t)
(delete-char -1))
