Codex Desktop Windows: light theme becomes mixed dark/light after resizing or reopening smaller window

Summary

On Codex Desktop for Windows, the default light theme can become a mixed dark/light theme after resizing the window or reopening the app in a smaller window state. This makes parts of the UI unreadable.

Environment

• OS: Windows
• App: Codex Desktop
• Theme: default light theme

What happened

The app was using the default light theme. After shrinking the window / reopening from a smaller window state, the UI suddenly changed into an inconsistent theme state:

• Initially, most of the UI appeared black and content was hard or impossible to read.
• Later, part of the settings content area became white again.
• The left navigation / app shell and top menu area remained dark/black.
• Text colors did not match the resulting backgrounds, so some text was nearly invisible.
• The foreground/text color was manually changed afterward only as a workaround to make text readable; it was not the trigger.

Expected behavior

When the default light theme is selected, resizing the window, minimizing/restoring, or reopening the app should keep the entire app consistently in the light theme. The app shell, sidebar, top menu, content area, and text colors should all be recalculated/applied consistently.

Actual behavior

The app appears to mix dark theme shell/background colors with light theme content colors after a window size/state change, producing low-contrast or invisible text.

Impact

This significantly affects usability because settings and navigation text can become unreadable until the user manually changes theme/foreground colors.
