Hello:
the below code seem to not work, is it child-frame's limit?
(make-frame
`((parent-frame . ,(window-frame))
(fullscreen . nil)
(alpha . 20)))

It's a limitation of the window manager. For example, it doesn't work
with Debian stable's xfwm4 here and it doesn't work with Windows XP
either. That's the main reason why I don't show eldoc info with child
frames but use classic tooltip frames instead. But ISTR that alpha for
child frames works with Windows 10 and there might also exist
compositing window managers for GNU/Linux that can handle it. So YMMV.

Dunno how important this info is, or whether this
is already done. But if it's not yet done, could
such info be added to some doc somewhere? (Thanks
for considering it.)

For the record it works on macOS as well.
