That may happen after a keyframe, if the congestion controller indicates
that there isn't enough throughput available to send the whole keyframe.
This is more visible when recording, since recording causes extra keyframes.

Strange, the picture should be exactly the same.  Are you using the same
video player?  Perhaps there's a sharpening filter in one player and not
the other?

Yes, if you have a good connection, then the congestion controller doesn't
limit the throughput.

Yes, it's unfortunately normal: WebRTC may change the video's resolution
at every keyframe (due to congestion or due to the user rotating their
phone), and we start a new file every time.

I've considered using a single file even when changing resolution, the
resulting video works, but it's not a technically correct Matroska file.

There's one already.  Just go to
