Comment (by pdr0):

 Replying to [comment:11 Balling]:
 > scale=sws_flags=sws_dither=0 is wrong. The correct command is
 scale=sws_dither=0 or scale=sws_dither=none (that is producing same
 results, somewhere none is made the same as 0). That makes a change in
 #3345, please test!! There is no such thing as sws_flags in scale only
 flags. While there is a separate -sws_flags option.

 You're rigth - "sws_dither=none" is the correct switch ,
 https://github.com/FFmpeg/FFmpeg/blob/master/libswscale/options.c

 "sws_dither=0" gives the same result... at least for now

 That 3345 ticket is 8 years old . OP claims that issue isn't present with
 libav. You get bit identical results with libav. Libav dithers by default
 too now too. Maybe it didn't 8 years ago.
