Where does the bug appear (feature/product)?
Cursor IDE
Describe the Bug
The current version of Cursor does not allow the use of Pylance and seems to rely on jedi-language-server, which makes Python environment discovery very slow. On a server with over a hundred environments, after restarting Cursor it takes several minutes to finish scanning the Python environments. During this process, you cannot select an environment, and it takes a few more minutes before syntax highlighting becomes available, whereas Pylance only takes a few seconds.
Steps to Reproduce
On a server with over a hundred environments, after restarting Cursor it takes several minutes to finish scanning the Python environments.
