Linux/Wayland: Ctrl+M dictation shortcut also minimizes Codex window

[barbudars]

Summary

On Linux/Wayland, holding Ctrl+M starts Codex dictation but also minimizes the Codex window.

Environment

• OS: Ubuntu 24.04
• Session: Wayland
• Package: codex-desktop 26.429.61741
• App: am-will/codex-app Linux build

Behavior

1. Open Codex App and focus the composer.
2. Hover the microphone button. The tooltip says: Click to dictate or hold Ctrl+M.
3. Hold Ctrl+M.
4. Dictation starts.
5. The Codex window then minimizes.
6. If the window is restored, dictation is still active.

Expected behavior

Holding Ctrl+M should start dictation without minimizing or switching away from the Codex window.

Notes

This looks similar to the upstream OpenAI Codex issue:

• Windows: Ctrl+M voice dictation shortcut can minimize window or trigger global hotkey conflicts openai/codex#14549

A good fix would be one of:

• use a safer default shortcut on Linux;
• prevent the minimize/window action from also firing;
• allow users to customize the dictation shortcut.

Ctrl+M appears fragile as a default shortcut because it can conflict with OS/window-manager/Electron behavior.
