❓ Problem: python3 -m venv venv opens a new window instead of running in the same terminal

Bug Reports

System: Ubuntu 24.04
Python: 3.12 (installed with APT)
Editor: Cursor
Shell: bash
Desktop environment: GNOME (default Ubuntu)
:magnifying_glass_tilted_left: What’s happening

When I run this command in the terminal or inside Cursor:

python3 -m venv venv

instead of just creating the virtual environment in the current terminal, it opens a new window (like a new terminal or cursor window). That’s not normal behavior.

:white_check_mark: What I already tried

python3-pip, python3-venv, and python3.12-distutils are already installed.

No alias for python3 (alias python3 returns nothing).

python3 -c "print('hi')" works fine — no new window.

Tried python3 -m venv venv --without-pip → same result.

:thinking: What could be wrong?

Maybe Cursor is handling the venv command in a weird way? Or maybe Ubuntu’s sandboxing or something like Snap is causing this?

:red_question_mark: My question

Has anyone seen this before?

Why would python3 -m venv open a new window instead of just running like any normal Python command?

Any tips or things I can check?

Thanks in advance! :folded_hands:
