The vignette effect isn't centered in the frame, if the default values for
x0, y0 are used:
ffmpeg -f lavfi -i color=white:size=8x8 -vf vignette=PI/4 -frames 1 -y
out.png
It would be better to use (w-1)/2 and (h-1)/2 as default values:
ffmpeg -f lavfi -i color=white:size=8x8 -vf
vignette=PI/4:x0=(w-1)/2:y0=(h-1)/2 -frames 1 -y out.png
