Environment

• App: Codex desktop
• Version: 26.429.61741
• Build: 2429
• Date observed: May 6, 2026
• OS: macOS
• Display setup: External monitor (BenQ SW321C), scaling set to More Space
• Main display: external monitor

When pets are enabled, the floating pet appears heavily clipped. Only the top-left portion of the sprite is visible.

Actual
Pet is clipped; only a small top-left fragment is visible.

Frequency

• 100% reproducible in this setup.

What steps can reproduce the bug?

1. Connect external monitor and set macOS display scaling to More Space.
2. Launch Codex desktop.
3. Enable/wake pet (/pet or via Settings > Personalization > Pets).
4. Observe pet rendering in overlay.

What I already tried

• Fully quit/relaunch Codex.
• Cleared persisted overlay state in ~/.codex/.codex-global-state.json.
• Reset avatar/window layout keys and overlay bounds.
• Forced overlay bounds to app-default geometry values.
• Created and selected custom pet package with scaled-down sprite content.
• None resolved clipping.

What is the expected behavior?

Full pet sprite should render correctly in the overlay.

Suspected area

• Pet overlay rendering/layout calculations under high-density or scaled external displays (DPI/devicePixelRatio/viewport clipping math).
