Problem description & steps to reproduce

The user textarea has extreme sluggish performance when typing when the conversation above has a lot of context.

1. Write a very long message (16K+ tokens) and send.
2. Try typing into the textarea. Sluggish performance. Are we rerendering a component like ChatScreen on each keystroke and doing complex computations on the previous messages? I can't easily spot it myself if we are.
