What steps can reproduce the bug?

  1. Use an Intel MacBook Pro.
  2. Download the official macOS Intel build of Codex Desktop from Codex for Developers.
  3. Install it by dragging Codex.app into the Applications folder.
  4. Open Codex.app.
  5. Log in with an OpenAI account.
  6. Open the main Codex Desktop interface.
  7. Observe that a large horizontal overlay/bar appears covering a significant portion of the UI.
  8. Try switching appearance between dark mode and light mode.
  9. Observe that the overlay/bar remains.

The Codex Desktop UI should render normally without any overlay/bar covering the interface, and scrolling should be smooth.
