Codex Windows tray icon is white/invisible on light hidden-tray overflow background

Summary

On Windows, the Codex tray icon appears almost completely white in the hidden tray overflow panel when the panel background is light. This makes the Codex tray entry difficult to see or identify.

Environment

• Product: Codex Desktop App for Windows
• App package observed: OpenAI.Codex_26.616.6631.0_x64__2p2nqsd0c76g0
• OS: Windows
• Tray location: Windows hidden tray overflow panel (^ system tray popup)

Steps to reproduce

1. Launch Codex Desktop on Windows.
2. Ensure Codex is present in the system tray / hidden tray overflow area.
3. Open the Windows hidden tray overflow panel on a light tray background.
4. Observe the Codex tray icon.

Current behavior

The Codex tray icon is rendered as a white/single-color icon. On a light tray overflow background, it becomes nearly invisible.

Expected behavior

The Windows tray icon should remain visible on light tray backgrounds, for example by using a colored icon, a high-contrast outline, or an adaptive asset suitable for Windows tray overflow UI.

Technical notes

Local inspection shows the Windows tray setup loads process.resourcesPath/codex-tray.ico from the installed app resources. The observed installed asset appears to be a grayscale/single-color icon, which explains the poor contrast on a light overflow background.

Attempts to replace the icon locally were blocked by MSIX/WindowsApps package protection, so this appears better handled as a packaged asset/UI issue rather than a user-side cache problem.

Additional context

Clearing Windows TrayNotify and icon caches did not resolve the issue. The underlying tray icon asset remains white/single-color.
