The sliding coloured band of testsrc is already enough to see the problem,
although slightly due to the gradient. It is even more noticeable with a
more contrasted source, such as one produced by drawtext:

ffmpeg -lavfi 'color=black:r=24:d=20,drawtext=fontfile=sans:text=!:fontcolor=white:fontsize=1000:y=-10:x=t*24-200,fps=fps=25' -preset ultrafast -y t.mkv
