Poor performance on 360 video on You
Tube which uses Web GL/Canvas
We're seeing poor performance on YouTube while viewing very high quality 360 video. It looks like YouTube do 360 by decoding a large video, and using canvas/webgl to transform it to a 2D viewport. STR: 1. Load 360 video on YouTube, i.e.: https://www.youtube.com/watch?v=HEEIzZ7UjRg 2. Select 4K from the cog menu 3. Pan the 360 video around by clicking and dragging, performance seems worse than Chrome. The settings/cog menu is less responsive (it's been reported that on some machine's the cog menu is extremely unresponsive). Here's a profile, which I think is showing that we're spending most of our time doing WebGL stuff on the content process' main thread: https://perfht.ml/2r0mEKc
