Safari on iOS 15 has a black horizontal outline when rendering own camera feed and when the screen is in portrait mode. Rotating the phone into landscape orientation "hides" the black box.

This is almost certainly related to how the current version of Safari interprets (or does not interpret) the orientation bits in the video stream.

Here is a test page: https://beaconx.com/data/apple-black-outline.html

This is affecting production apps. User experience is significantly degraded - the video of the other call participants (for video conferencing scenarios) are being covered by the black box.
