This is so close to being fixed!

I am guessing this is just capture/playback code issue? You have a portable WebRTC stack in rust https://github.com/webrtc-rs/webrtc

I haven't used Tauri myself but this sounds like a fun thing to go fix. Silly this is a blocking issue.

I think I wound up hacking something in Rust which is less than ideal felt hackish, at that point I was better off just remaking the UI in an actual native UI stack.

Still too many Rust UI stacks are GPU driven.
