New description:

 Summary of the bug:
 From debugging the issue this seems to happen only when video resolution
 is not divisible by 32.

 How to reproduce:
 {{{
 ffmpeg.exe -ss 00:00:00.50 -i test.avi -vframes 1 -pix_fmt rgba test.png

 ffmpeg version N-103795-g140eac77a9-g6e26015a6b+1 Copyright (c) 2000-2021
 the FFmpeg developers
   built with gcc 10.3.0 (Rev5, Built by MSYS2 project)
 }}}

 This may be same report as #8871, but in this case8 px on left side are
 corrupted.
 This issue happens in Blender, but there every line of output is corrupted
 like this.
