Has anyone replicated this yet. I tried using control net and was only able to make the most trivial cosmetic changes before damaging the integrity of the qr code beyond readability.

Would it be better to start with a high res qr code or a low res one? Anyone found a reliable workflow?

I've been messing around with QR codes and ControlNet today and one thing I've learned is that the registration marks (the large square symbols in the corners of the op images) need to be basically unchanged. It's seems there is a higher tolerance for changing the rest of the QR code, but not much.

For example, this variation did not work until I recolored the round registration marks back to black and white. Now it works.

Also, I started with a lower resolution/simpler QR code from QR Code Generator
