I have phantom text problems in JupyterLab.

I type text in a cell, the text shows on the screen, but the cursor stays where it is (it should move after the typed text), then the text I typed disappears and the cell runs with the old text.

Here is a screencast:

Can you help?

It was the notebook-intelligence extension.

Disable it and enable the stock completer with:

```auto
jupyter.exe labextension disable @plmbr/notebook-intelligence
jupyter.exe labextension enable @jupyterlab/completer-extension:base-service

```
