Can't seem to reproduce. Can you show me the screenshot including the whole window?

Hope it helps:

Thanks!

The suggest widget should not be rendered when the cursor is not visible:

e.g.

It can still fly out of the editor when the window is resizing.

I could reproduce. The root cause is no longer that the editor content widget positioning code is flaky, but that the suggest widget reports a very large width (also with transparent stuff, presumably where suggestion details might sit)

So, the problem is with the suggest widget which sizes itself at twice the width of the visible stuff inside of it:

I've pushed a fix to not allocate space for the details/docs section until an item in the list does have details/docs to show.

This will help the above case where textual completions don't have any details/docs to begin with.

Note: This doesn't stop from the suggest widget to flowing into the side bar if there is no space.
But, it does make the suggest widget occupy the space right below the cursor rather than assuming that there are docs and having ghost space.
