Long git diffs create lag in Codex App

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

Version 26.305.950 (863)

What subscription do you have?

Pro

What platform is your computer?

Darwin 25.2.0 arm64 arm

What issue are you seeing?

If a thread has a huge git diff staged it causes the app to become extremely laggy. I at one point had +200,000 showing in the toggle git diff panel button and it caused the app to use a huge amount of memory and become extremely slow. Lag remains whether the thread with the huge diff is open or not. Committing changes and pushing fixed the lag.

What steps can reproduce the bug?

1. Have a huge git diff build up in a thread.

What is the expected behavior?
