Didn't work on Chromium, Version 117.0.5938.132 (Official Build) Arch Linux (64-bit). Console errors: https://pastebin.com/XSpEzhZW
As one of the folks using Linux, I'm hoping that this will get resolved sooner rather than later, too. (Well, actually - I'd prefer Firefox get support, but that looks like it might take longer. Alas.)
Rest assured we'll have this sorted for the next release; we were aware that Linux/Chrome/WebGPU were incompatible, but we didn't bubble that error up correctly. Our bad!
As I mentioned in another comment, we're considering adding a fallback renderer, but our hope is that Firefox will be able to complete its implementation sooner rather than later - as a Firefox user, I would much rather use it than Chrome myself!
