SemanticHighlighting doesn't work without reloading window in Python Cursor

[Hoony0321]

When writing Python code in Cursor, newly created variables do not receive semantic highlighting (e.g., color for variable names). However, when I restart Cursor, the correct colors are applied.

This only happens for new variables written after the editor launches — existing variables are highlighted correctly.

---

Steps to Reproduce

1. Open a Python file in Cursor.

2. Write a new line, e.g., my_var = 123.

3. Notice the variable name my_var does not get semantic highlighting.

4. Restart Cursor.

5. Now my_var is highlighted properly.

Environment

• Cursor version: [you can get this via Cmd+Shift+P → “About Cursor”]

• OS: macOS / Windows / Linux (choose yours)

• Python extension installed: Yes

• Pylance extension installed: No (not available in Cursor)

---

Things I Tried

• "editor.semanticHighlighting.enabled": true

• "python.languageServer": "Pylance" (but Pylance is not listed in extensions)

• Reinstalling the Python extension

• Reloading the window

---

Notes

This issue does not happen in VS Code with Pylance installed — new variables get highlighted immediately.

Is this an issue with how Cursor handles the Python extension or semantic tokens?

Would appreciate any insight or fixes
