We’ve encountered a performance issue during Zoom screen sharing. When **User A** shares their screen, **User B** is able to see the shared content, but it appears **laggy and not smooth** on User B’s side.

You can try replicating the behavior [here](https://videosdk.dev/uitoolkit/)

This issue affects the viewing experience, especially when sharing content that involves animations, video, or frequent screen updates.

Steps to Reproduce:

1. Start a Zoom meeting with two users (User A and User B).
2. User A shares their screen.
3. User B views the shared content.
4. Notice that the screen appears choppy or delayed on User B’s side.
