Windows 11: Download/Close buttons overlap native window controls in image preview

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

26.601.10930

What subscription do you have?

Plus

What platform is your computer?

Windows 11 x64

What issue are you seeing?

When viewing an image attached to a patch or prompt in the Windows version of the Codex app, the image viewer's controls (Download and Close) overlap with the native Windows title bar controls (Minimize, Maximize, Close).

This causes the buttons to partially cover each other and results in a broken UI layout.

What steps can reproduce the bug?

1. Open the Codex desktop app on Windows 11.
2. Open a patch or prompt that contains an image.
3. Click the image to open the image viewer.
4. Observe the top-right corner of the viewer.

The image viewer controls overlap with the native Windows window controls.

What is the expected behavior?

The image viewer controls should be positioned so they do not overlap with the native Windows title bar buttons.

Both sets of controls should remain fully visible and accessible.

Additional information

• OS: Windows 11
• The issue occurs in the image preview/viewer.
• Screenshot attached.

It looks like the image viewer is rendering its own top-right controls without accounting for the native Windows title bar area.
