Comment (by Videogamer555):

 Replying to [ticket:9192 Videogamer555]:
 > Summary of the bug: When using the -sws_dither command line switch to
 disable dithering with the value "none", it still behaves as if it was
 using the default value of "ed" (which is error diffusion dithering).
 > How to reproduce:
 > {{{
 > % ffmpeg -i video_in.avi -swf_dither none animation.gif
 > ffmpeg version is latest nightly Windows build "N-101948-g870bfe16a1
 -ffmpeg-windows-build-helpers"
 > built on April 14, 2021
 > }}}

 Note that where it says -swf_dither, it SHOULD say -sws_dither. I
 accidentally typed an "f" where there should be an "s". But I can't edit
 my original post, so I'm putting the correction here as a comment.
