Does changing zoom setting affect fingerprinting?

I am following the guides, using Mullvad browser and Tor. I am told not to change any settings.

Does this include the default zoom setting?

And if so, does it make a difference if I am, by default, on 130% … compared to being on 100% but zooming into 130% every time I load a page?

afaik, yes.

this is why RFP prevents zoom state from saving.
