UX for Chat in the ChatGPT Mac App

What version of the Codex App are you using (From “About Codex” dialog)?

What subscription do you have?

What platform is your computer?

Darwin 24.6.0 arm64 arm

What issue are you seeing?

1. When I submit a prompt, the response streaming is not smooth and the response leaves a large whitespace on my screen (basically the last line of the response is near the top of my screen instead of being at the bottom near the text box).
   As soon as I submit the next prompt, the whole screen jumps which is displeasing, to remove the whitespace for the next response stream. And then the same thing described above happens.
   The wesbsite does not have this just the app.

2. Also there are random UI in the response which don't have any connection to the response.

3. The reference modals are distracting, as every time the response is referencing a document, it creates a distracting box that breaks the flow of the response and makes it harder to read
