[Linux/XFCE] ChatGPT Desktop 26.818.61809 emits protocol, feature-key, listener, and Chromium errors on startup #40412

What version of the Codex App are you using (From “About Codex” dialog)?

ChatGPT Desktop 26.818.61809 from the official OpenAI Linux DEB stable repository.

Bundled Codex CLI/app-server: 0.149.0-alpha.4.3.

What subscription do you have?

ChatGPT Plus.

What platform is your computer?

Linux 7.0.0-30-generic x86_64 x86_64

Linux Mint 22.3, XFCE, X11.

What issue are you seeing?

Launching the official Linux desktop app from a terminal succeeds: the window becomes ready, the bundled app-server initializes, account lookup succeeds, and the local connection reaches connected. However, startup emits several internal errors and warnings:

Failed to register codex:// protocol handler isPackaged=true

(node) [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications.

(node) [DEP0180] DeprecationWarning: fs.Stats constructor is deprecated.

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 destroyed listeners added to [WebContents]. MaxListeners is 10.

Electron renderer console [warning]: Matched leaf route at location "/" does not have an element or Component. This means it will render an <Outlet /> with a null value by default resulting in an "empty" page.

ignoring invalid experimental feature enablement keys: apps_mcp_path_override

Electron renderer console [error]: RequestError: Failed to fetch undefined

Registration response error message: DEPRECATED_ENDPOINT

The apps_mcp_path_override warning is propagated as a connection-failed error by the remote-connections manager even though the same event reports state=connected.

The application remains locally usable, so these are not startup-fatal errors. They appear to be multiple packaging/runtime compatibility issues rather than a missing system dependency.

What steps can reproduce the bug?

1. Install the current chatgpt package from OpenAI's official Linux DEB repository.

2. On XFCE/X11, ensure no ChatGPT process is already running.

3. Start the app from a terminal:

   chatgpt

4. Wait for the main window and backend initialization to complete.

5. Observe the messages above on stderr.

6. Exit with Ctrl+C.

The app-server initialization itself succeeds in roughly 0.5 seconds and the main window reaches ready-to-show.

What is the expected behavior?

• Startup should not emit deprecated Node API warnings from packaged application code.
• The codex:// handler should register consistently on supported Linux desktop environments.
• Desktop feature flags should be compatible with the bundled app-server and should not mark a connected remote manager as connection-failed.
• Electron windows should not exceed the default listener limit during normal startup.
• The renderer should not issue a request with an undefined target.
• The bundled Chromium runtime should not attempt registration through a deprecated GCM endpoint.

Additional information

Protocol-handler checks show an integration mismatch:

$ xdg-mime query default x-scheme-handler/codex
chatgpt.desktop

$ gio mime x-scheme-handler/codex
No default applications for “x-scheme-handler/codex”

XFCE reports that xdg-settings get default-url-scheme-handler codex is not implemented.

Additional isolation evidence:

• apps_mcp_path_override is not present in the user's Codex or desktop configuration.
• Authentication succeeds (authenticatedAccountPresent=true, result=succeeded).
• The bundled Codex app-server handshake succeeds.
• No missing shared libraries, GPU initialization failure, fatal sandbox error, or native crash was observed.
• 26.818.61809 is currently the installed and candidate version in the official repository.
• The feature-key warning appears related to Unable to enable Remote Control on Mac #38095, but this reproduction is on Linux and also captures the protocol registration, listener, renderer-request, and bundled Chromium errors.

No account identifiers, local task IDs, private paths, tokens, prompts, or raw logs are included.
