Codex chat cannot scroll to the newest output

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Cursor version: 1.3.14.7 (Universal)
OS: macOS 15.6 (Darwin 24.6.0)

Issue: When I use the Codex agent in Cursor, the newest assistant output becomes hidden behind the fixed composer/control area. The chat cannot scroll far enough to bring the hidden content into view.

Expected: I should always be able to scroll to and read the entire newest message.

Actual: The lower part of the latest message is obscured and inaccessible.

Reproduction: Use Codex in a conversation long enough to produce substantial status/output content, then scroll to the most recent response.

Evidence: I will attach a screenshot showing the newest output hidden behind the composer.

Steps to Reproduce

I closed it then open it at it fixed it for a little bit then got stuck again

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the report and the screenshot. From the UI in the screenshot, this is the OpenAI Codex extension panel openai.chatgpt, not Cursor’s native UI. Codex uses its own chat webview that’s separate from Cursor. The newest output not scrolling and getting hidden until you “nudge” the panel, and close/reopen helping for a bit, is a known issue on the extension side.

What to try:

  • Scroll up a little and then back down, or click inside the panel to refocus it so the content redraws. This is the same effect as close/reopen, just faster.
  • Update the Codex extension to the latest version. In Extensions, find Codex, update it, then run Reload.

Since this is OpenAI’s extension code, not Cursor, it needs to be fixed in their tracker. If it still happens after updating, please post a report with a screenshot at GitHub - openai/codex: Lightweight coding agent that runs in your terminal · GitHub. There are already similar scroll issues for the panel, like #13159, #17527, so you can add your details there.
