Squares generated with classic option slightly too large

[jasperhabicht]

It feels as if the squares that are generated using the classic option are a tad too large or maybe a stroke is drawn around them?

MWE:

\documentclass{article}
\usepackage{fancyqr}

\begin{document}
\fancyqr[color=black, classic]{https://www.google.com}
\end{document}

Note that this is especially (only?) visible when creating a relatively small QR code and zooming into it:

Oh thank you very much! I probably forgot to reduce the compensation for non-rounded squares and will get to it asap!
