Copilot in GitHub

Body

I downloaded and ran the Github Copilot Desktop App on Linux (Fedora + Wayland + Sway).

The issue is that it seems that it cannot open the browser at all. In the initial sign in, the "open browser" button did nothing. I still could continue by manually navigating to https://github.com/login/device in my browser and entering the code.

Now, when I want to setup an MCP server I have the same issue. I configure it, then click the sign in button and just see the spinner icon, but nothing happens. I assume that is when it tries to open the browser as well.

The console output when I try to do it - I am not sure if thats relevant or not:

2026-06-11T12:01:05.706292Z DEBUG task_spawn{task="ws_handle_connection"}:task_spawn{task="ws_recv_loop"}: github_app::websocket: received message text={"type":"start_mcp_oauth_login","name":"Atlassian","client_name":"GitHub Copilot","callback_success_message":"You can close this window and return to GitHub Copilot."}

** (github:212762): WARNING **: 14:01:07.275: atk-bridge: get_device_events_reply: unknown signature

Anyone else with that issue, or an idea how to fix it?
