Comment (by Llyw):

 Final update: I just had the opportunity to retry my reproducer command
 with an updated FFmpeg build (based on
 [https://github.com/FFmpeg/FFmpeg/commit/e3580f6077 FFmpeg at e3580f6077])
 and can confirm that the geometrical distortion as observed in this defect
 has been fixed with the most recent changes, as evident when comparing the
 newly added attachments
 https://trac.ffmpeg.org/attachment/ticket/9781/Output_zscale_5.0.1.png and
 https://trac.ffmpeg.org/attachment/ticket/9781/Output_zscale_git-
 e3580f6077.png that show the `zscale` output of FFmpeg 5.0.1 and the
 result obtained using the aforementioned git revision, respectively.
