High CPU usage in VS Code when opening Codex panel in a non-Git workspace

Which IDE are you using?

VS Code

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

Opening the Codex panel in VS Code causes CPU usage to spike immediately and remain high. Disabling the Codex extension and restarting VS Code makes CPU usage return to normal.

This appears to happen when the current VS Code workspace is not a Git repository.

Environment:

• OS/platform: Darwin 25.4.0 arm64 arm
• VS Code: 1.118.1
• Codex VS Code extension: openai.chatgpt@26.422.71525
• Architecture: Apple Silicon / darwin-arm64
• Workspace type: local folder, not a Git repository

Observed high-CPU processes:

• Code Helper (Renderer): roughly 90% to 200%+
• Code Helper (Plugin): roughly 30% to 50%

What steps can reproduce the bug?

1. Open VS Code with a folder that is not a Git repository.
2. Enable the Codex VS Code extension.
3. Open the Codex panel/window.
4. Observe CPU usage in Activity Monitor or VS Code Process Explorer.

What is the expected behavior?

Codex should handle non-Git workspaces gracefully. Opening the Codex panel in a folder that is not a Git repository should not cause sustained high CPU usage, repeated Git metadata requests, or log flooding.
