Bug Description

Here's a videos for demonstration of the bug:

As seen in the video it takes too long to update the completion menu while typing without taking breaks.

Does the issue still occur if you disable prefetch_on_insert? That's mostly a proof of concept, I'll add a warning

Yes it indeed occurs even after disabling prefetch_on_insert.

Thanks @ribru17 , cant believe lua_ls was the reason behind that. Closing this now
