I’m encoding with WebRTC as well as playing back the stream via WebRTC.

I am seeing some occasional green artifacts as well as screen tears.

Additionally, there seems to be an issue after long periods of time where audio becomes gargled and the video slows down.

What could be the cause of these issues?

This would be due to UDP packet loss. Please move to TCP if possible.
