From Dustin Kerstein: > https://jsfiddle.net/qz9ka6xm (using RGBA textures from a very simple cycling color video) > My MacBook Pro + older Safari used to be able to hit 50+ fps on that test consistently, and now it's ~20fps regardless of enabling GPU Process WebGL and/or WebGL Metal. > Big Sur 11.6. May be related to bug 232235

Note that there are important steps to take when updating ANGLE. See https://trac.webkit.org/wiki/UpdatingANGLE

The original problem might be mostly mitigated by bug 231425
