Background color artifacts in prototypes

Hi, I have an issue with prototype views in Chrome and Edge Chromium.
When I share a design, it looks bugged or messy, with white backgrounds with a noisy pattern or completely gray. Here's an example:

Also, as you can see, there are scroll bars in the view, which I don't know why appeared.
That's happening when I view it at 100% scale in the Prototype link.
However, if I change the scale at 99%, everything looks as intended.

Has anyone had this issue? It's annoying because I can't embed my prototypes for feedback since embeds don't have zoom, and it's also a waste of time to check the link only to zoom it at 99% to interact properly with the prototype.

I'd appreciate any kind of help on this.

Thank you
