oh my. +1 for calling this out <3
I can link the github directly if it's helpful or send you info. I do apologize for this.
Seems the animate:requestAnimationFrame fn in the header and footer (headerBoid.js,footerBoid.js) animations are locking some UI threads (adding too many events on stack?).
Firefox seems fine, and I was able to get the gist of the product.
Seems like a good problem to solve, especially for companies that offer libraries (ex: Samsung Tizen dev. environment) or education/enterprises that have a lot of students/interns, as setting up the environment properly could be a significant chunk of the time spent learning/working.
Good luck to the team!
