this is on emacs built from Git @head running on Debian under StumpWM
as a window-manager.
Try:
(add-hook 'focus-in-hook #'(lambda () (message "hello %s" (selected-frame))))
What you'd expect:
1. See "hello <frame-id>" when Emacs frames receive focus.
2. Nothing when Emacs loses focus.
What Actually Happens:
Hook fires when emacs loses focus, and you see "Hello <frame-id>"
where frame-id is the id of selected frame in emacs
2. You get "hello" when Emacs receives focus -- with no frame-id.
Note that the corresponding focus-out-hook appears to work correctly
i.e. only fires when Emacs loses focus.

Can you try a different window-manager? It could also depend on the
focus policy, I think.

It works as expected here, but I'm not on X.

Am bound to stumpwm because it talks to me -- I hope someone else on
the list can try different WMs.

emacs26 on Debian here, with openbox.
Using the posted recipe with emacs -Q I get a message like
| hello #<frame *Messages* micha@drachen 0x1174c30>
two times (!) when Emacs loses focus, and three times when I Alt-Tab
switch back to Emacs.
Michael.

I get the expected behaviour using i3 with emacs26 on Debian.
One "hello #<frame...>" message per time I bring Emacs into focus.
I do seem to get a spurious message if I unfocus Emacs, switch to
another workspace and then back again; Emacs is still unfocused, but
it prints a "hello #<frame...>" message. Possibly the workspace
switching is implemented behind the scenes by first raising every
window in the workspace?
