The goal of the WebGL Working Group was for failIfMajorPerformanceCaveat to allow websites to make better choices about which content to serve to users, ideally via offering a choice to users.
I no longer think that this is useful here, or rather it's only ever useful in the very narrow case: When a website does indeed have a fallback ready, and the fallback does actually have better perf. Today this is only true on some Windows systems that have cpu-emulated webgl, but gpu-accelerated canvas2d, but this is not most systems. Simultaneously, we've seen a disappointingly large set of websites break for users that hit the failIfMajorPerformanceCaveat path. Since the usefulness of failIfMajorPerformanceCaveat is very limited, and many sites don't cooperate with us (as the user's User Agent), I think it's best to disable failIfMajorPerformanceCaveat for the time being. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905054 Title: Firefox 83 Breaks WebGL To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1905054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
