Description Kimmo Kinnunen 2021-10-25 23:50:24 PDT 
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.

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