As requested by Eli on reddit, a proper bug report about the company issue:
Using the new native line numbers in emacs -q
alongside company mode results in line numbers not being rendered in
lines where the company-mode popup is active. This is the same as in
(n)linum-mode, however the company popup, except the first line, is also
shifted to the left into the space line numbers used to occupy:

It looks like there's a general issue of overlay using packages not
expecting the space now being used by line numbers. For example the
fill-column-indicator package draws its indicator too far to the left
and swerves off with the comments at the top for some reason:

(Don't know why the company popup looks even worse here, that doesn't
happen when I load my full config).

Very cool. In that case, let's consider this issue resolved.
I've already pushed this fix and cut a new release now.
(If you think posn-at-point takes that information from what is
displayed on the glass, or from some of its internal representation,
then that's not what it does, because the internal representation of
what's on the glass is many times outdated when a Lisp program runs,
so it cannot be trusted.)
I was thinking there was some change canary (or many of them), and the
"internal representation" is recomputed when any of those values change.
