OK, so I'm writing this using Wayfarer 3... Generally more things work than I've expected. Had to fix pixel format conversions for example, but it seems that most of the JavaScript is fine - Void Linux JS patches are still there and working. I got OffscreenCanvas to work, which I couldn't get working with Wayfarer 2. Surprisingly, Cloudflare browser check appears to pass now (don't hold your breath, they may break it at will). One thing that so far refuses to work is Google Street View (renders all black). Media playback appears to work, and I was indeed able to repro the same issues with seeking in iOS mode as was reported here. Will take a look at that next I suppose...
