Can you try with Chrome dev (Google Chrome Developer Tools - Google Chrome)?
It seems in the latest version of canary they added some checks that make some PGs to fail (for eg: https://playground.babylonjs.com/#YX6IB8#31) but I can’t debug for the time being because my Canary does not work anymore locally (it seems there’s a bug in Canary: 1276536 - chromium - An open-source project to help move the web forward. - Monorail)
[EDIT] It seems the problem is related to using storage textures in compute shaders, so likely not your problem. I would need a repro to try to figure it out. Note that you must use Canary and not regular Chrome because the latter is not up to date and we are using an API which is not in this version yet (in this PG you will get the error “Invalid destination gpu texture format.” in regular Chrome).
