STRs:
 1. Open https://appear.in/someroom2456245 and share cam+mic
 2. Move around or move hand in front of camera.

Expected result: Normal smooth self-view.

Actual result: Severe smearing making video look like an art exhibit or oil-painting. See attached image.

I can reproduce it fairly reliably, though not 100%. Seems to happen more with appear.in than in a fiddle.

Workaround:
  Setting media.hardware-video-decoding.enabled=false and restarting Firefox seems to cure it.

Attached video video of the problem
I've been able to repro. Restarting firefox fixed it _without_ flipping the pref mentioned in comment 0.

This is gUM -> HTMLMediaElement no PeerConnection of other things involved.
there's no hardware decoder even used on mac with vp8/vp9

media.hardware-video-decoding.enabled=false is not involved in webrtc decoding.
