Hi,

When opening a rather big image into a quite big Emacs window, movements
(C-n, C-p, C-f, C-b) are smooth at original image size but are jerky
whenever there is some zooming (in or out) involved.

Recipe:
        - emacs -Q
        - 'C-x C-f' "a big image.jpg"
        - 's o' (image-transform-reset-to-original)
        - keep 'C-n' pressed, keep 'C-f' pressed -> movements are smooth
        - 'i -' (image-decrease-size)
        - keep 'C-n' pressed, keep 'C-f' pressed -> movements are jerky

Best regards,
