We have a known Chrome bug that has been reported and our team met with our stream host engineers and have defined the bug as a direct Chrome issue. The Chrome team is working on this and will fix this on their next release. For now, our stream host is working on a resolution to patch this bug for now. The bug is related to the slightest bit of packet loss(decrease in internet speed), when this happens the quality for that individual on screen drops and gets locked in for the entire broadcast as a response from Chrome. You can read more about the Chrome issue on their website here: https://bugs.chromium.org/p/webrtc/issues/detail?id=10142
If you would like improved video quality until this fix is available, please broadcast from Firefox.
