I see the SAME bug on win 10 (61.0.3128.0/dev) when doing a h264 loopback call ie. https://appr.tc/?debug=loopback&vsc=h264

I do NOT see the bug if I do Win 10 (stable, 58.0.3029.110 ) to Mac (stable, 58.0.3029.110)  AppRTC call

I do NOT see the bug if you replace h264 with vp8/9 in the above steps

Devices used to produce the bug:
Win 10:  Logitech c930e or Microsoft LifeCam HD-3000
MacOS: inbuilt FaceTime camera
