What platform is your computer?

macOS 27 Public Beta

What issue are you seeing?

The macOS desktop app's red, yellow, and green traffic-light window controls are visible, but clicking them does not perform their expected actions.

The affected controls are:

• Red: close the window
• Yellow: minimize the window
• Green: zoom or enter/exit full screen

This is a functional click-handling issue, not a visual clipping or alignment issue.

What steps can reproduce the bug?

1. Open the Codex desktop app on macOS 27 Public Beta.
2. Locate the red, yellow, and green traffic-light controls in the title bar.
3. Click each control once.
4. Observe that the corresponding window action does not occur.

What is the expected behavior?

The traffic-light controls should respond to clicks normally and perform their standard macOS actions: close, minimize, and zoom/full screen.

Additional information

• This report is for Codex App version 26.825.51511, which is newer than previously reported versions of this issue.
• The issue affects the macOS desktop app's native window controls.

No source file, test, or entry point is named. First reproduce the click failure on macOS 27 Public Beta with Codex App 26.825.51511, then locate the desktop window title-bar and native traffic-light event handling. Done means red, yellow, and green controls perform their standard close, minimize, and zoom/full-screen actions.
