[nicolasbock]

Type: Bug

• VS Code Version: 1.88.1 (from snap, version e170252f)
• OS Version: Ubuntu 24.04

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?

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.
