Comment (by eelco):

 This is a rounding bug that happens because all subtitles are passed
 through the ASS code, which has a lower precision. I fixed this a while
 ago for SRT in our FFmpeg fork (see
 https://github.com/tupil/FFmpeg/commit/f0e98dd3b1e21abe1a83f8ac0d85f8fbf3ae47e7).
 I will supply a patch to ffmpeg-devel soon.
