Expected Behavior

Using this as a Browser Source : https://outer-wilds-anim-6zl8zgucn-xurei.vercel.app/

A comparable FPS using the Browser Source compared to Chrome/FF

Current Behavior

The framerate is really laggy (~5FPS).

Steps to Reproduce

1. Create a Browser Source with this URL : https://outer-wilds-anim-6zl8zgucn-xurei.vercel.app/ (dimensions 2560x1440)
2. Compare with the same page on Google Chrome or Firefox (with 75% zoom on a 1080p screen)

Anything else we should know?

Note that the page is not optimized at all. I'm actually more interested for an explanation of the underlying cause rather than an actual fix of the issue.

I tested it on Windows and the animation is fluid.
