Interesting that there is a flatpak build as well. I knew it was possible to run cli programs with flatpak but this the first programm i see that explicitly lists that as an option.

Like literally pull my disk out of a gaming nvidia machine, and plug it into my AMD machine with full working graphics.

This should work already, i switched from nvidia to amd this year by swapping the cards and removing the nvidia drivers some time later.

I guess it's because the drivers only apply to their specific hardware, so no problems having amd and nvidia drivers present at the same time.

Even if you would be able to track js code like that, the js code can react to it's own sideeffects. E.g. have 8 Elements and encode the 8-bit Fingerprint as a custom style sheet that adds an animation some of the 8 elements. Then react on the animation events and rebuild the fingerprint. It's virtually impossible imo. Maybe it can even be formal proven.
