Steps to Reproduce:

1. Create terminal.integrated.profiles.linux:

        "tmux": {
            "path": "tmux",
            "args": ["new-session", "-A", "-s", "vscode_${workspaceFolderBasename}"],
            "icon": "terminal-tmux"
        },

2. Open project
3. Open terminal (View: Toggle Terminal)
4. In the terminal, ask tmux to list-sessions:

10: 1 windows (created Fri Apr 26 07:32:01 2024) (attached)
vscode_workfolder: 1 windows (created Tue Apr 23 13:52:52 2024) (attached)

5. List clients (tmux:list-clients)

/dev/pts/10: 10 [80x30 xterm-256color] (attached,focused,UTF-8)
/dev/pts/13: vscode_workfolder [172x28 xterm-256color] (attached,focused,UTF-8)

6. Find PPID of client

$ ps -ef | grep 1192836

Moving this to VS Code as this has nothing to do with python extension.

[nicolasbock]

Thanks @karthiknadig . Just to clarify: I did the extension bisect and this issue only occurs with this extension being active in a Python project. Why is this issue then not related to the extension?

[meganrogge]

Reassigning to you based on the above comment @karthiknadig

[karthiknadig]

@nicolasbock It wasn't clear from the initial issue that this was specific to python. I can move this back to Python.
