--- Comment #6 from Erik Zivkovic <erik at zkc.se> ---
Using gl.RGBA made texImage2D drop from 64.6ms to 6.9ms in my latest test.

I am using a MacBook Pro (16-inch, 2019) 2,6 GHz 6-Core Intel Core i7, 32 GB 2667 MHz DDR4, AMD Radeon Pro 5300M 4 GB / Intel UHD Graphics 630 1536 MB

We are not using createImageBitmap anywhere in our code. The video source is a HLS video (about 4k resolution) and using HLS.js (MediaSource extension).

Using gl.RGBA mitigates the issue, so thanks for that!
