codex - 💡(How to fix) Fix Windows: Codex App UI renders as transparent/blank white content area

What issue are you seeing?

The Codex desktop app UI is rendering incorrectly on Windows.

Actual behavior:

• The left/sidebar area appears transparent and shows the Windows desktop wallpaper/icons behind the app.
• The main content area renders as a large blank white panel.
• The app menu/sidebar labels are visible, but the conversation/content area does not render correctly.
• No visible error message is shown in the UI.

Expected behavior:

• The Codex app window should render with an opaque background.
• The sidebar and main conversation/content area should display normally.

Steps to reproduce:

1. Open the Codex desktop app on Windows.
2. The app window loads.
3. Observe that the sidebar/background is transparent and the main content area is blank white.

Environment:

• Codex App version: 26.527.31326
• OS: Microsoft Windows NT 10.0.19045.0 x64

I attached a screenshot showing the rendering issue.
