Show full camera view on fullscreen

When having a video call in DMs and setting the other person to full screen, your own camera preview for yourself is now only a square, even though I'm sending over vertical video with my own camera. This is problematic, as I now don't know what is in frame or not.

Please revert this or introduce an option to see one's full view. I would much rather have calls with my girlfriend where I could see her whole camera view and she could see mine, like it used to be. Instead we now have to guesstimate what is being seen.

I also don't understand the need to have a gradient background during voice calls. I specifically did not set any of the gradient nitro themes because I don't like them.
