That could be it, I thought pixi would handle that automatically. Hopefully that should be the main issue then.
Edit: Could re-create the issue thanks to your tip, got lucky that there was a pixijs update a few days ago which provided a automatic fallback so it took less work than I was expecting 😅
Odd, happy it worked for you but I'd still expect it to work on the other pc's as well given that I'm using pixi.js which should be well supported. I'll tweak the build process to see if that helps.
Thanks! My plan was to add research to make things more interesting but sadly ran out of time. So in light of that I made it on the short side to avoid it becoming a chore 😅
