 Summary of the bug:
 How to reproduce:
 {{{
 % ffmpeg -i skew.png -vf
 "scale=force_original_aspect_ratio=decrease:w=2048:h=2048, thumbnail"
 -frames:v 1 skew_thumb.png
 ffmpeg version 5.1.2
 built on OSX
 }}}

 For certain PNG image resolutions, the command results in a skewed output.
 I am attaching examples of a PNG that does not cause the skew, and one
 that causes it.
 Previous versions of ffmpeg were not exhibiting this behavior
