Note on company-mode overlay pop-up

By default, the company-mode pop-up that lists completion candidates is drawn using an overlay. This creates alignment issues every time it is placed above a piece of text that has a different height than the default.

The solution recommended by the project’s maintainer is to use an alternative front-end for drawing the pop-up which draws child frames instead of overlays.^[1][2]

Also consider the corfu package.
