1. emacs -Q -fn "Dejavu Sans Mono-10"
2. Sanity check:
a. Move mouse cursor over a tool bar icons and observe that the
tooltips have their normal appearance.
b. Type `C-x 5 2' and observe that the newly created frame has its
normal appearance, the type `C-x 5 0'.
c. M-: (eq (selected-frame) (previous-frame))
=> t
3. M-: (redirect-frame-focus (selected-frame) (previous-frame))
a. Move mouse cursor over a tool bar icon and observe that the
tooltip is translucent and very light, barely visible.
b. Type `C-x 5 2' and observe that the newly created frame is
likewise translucent and barely visible.
Subsequent frames created by typing `C-x 5 2' in the first frame all
have the same translucent appearance. However, if I type `C-x 5 0' in
the first, normal-looking frame, thereby deleting it, then from the
translucent frame type `C-x 5 2', then the newly created frame has its
normal appearance, including tooltips, and typing `C-x 5 2' in this
frame creates a normal-looking frame. (But now repeating step 3 again
has the same shadowy results as before.)
I don't know when this effect of redirect-frame-focus began (I guess
since the unicode merge, though I only started seeing it recently after
reactivating some old code I have that uses redirect-frame-focus); I do
not see it with Emacs 22. Also, while I get the translucent tooltips
with both the x and xft font backends and regardless of font used, the
appearance of the translucent frame is more restricted: I see it with
-fn "Dejavu Sans Mono-10" with both backends, but only with the xft
backend with -fn "Dejavu Sans-10", -fn "Adobe Times-12" or -fn "Adobe
Helvetica-12" (the latter two are not defined under the x backend); with
other sizes of all of these fonts I don't get a translucent frame (but
still get translucent tooltips).

I can confirm that 3a is reproducible on Windows too (even without steps
1 and 2), but I do not see 3b (but that seemed to depend on font,
font-size and font-backend in your tests, so maybe there is a different
combination that can reproduce 3b on Windows).
I would guess this was introduced when the transparency patch went in or
some time after, rather than by the unicode merge.

This seems likely; indeed, when I start Emacs like this:
$ emacs -Q --eval "(setq default-frame-alist '((alpha . 30)))"
and then type `C-x 5 2', the newly created frame has about the same
appearance as what I see after calling redirect-frame-focus.
(Interestingly, and something I failed to notice in my OP, the tooltips
generated from the transparent frame are not transparent; i.e., in the
case of my OP, only the tooltips of the first frame are transparent).

(I'm going through old bug reports that unfortunately wasn't resolved at
the time.)
I tried this recipe in Emacs 28 under Debian/bullseye, and I couldn't
see anything unusual. Are you still seeing this bug in recent Emacs
versions?

No. At the time I had observed the problem with the x and xft font
backends; I currently only have a build of emacs-26 with the xft
backend and cannot reproduce the problem there either. So I assume it
was fixed, or anyway stopped being a problem, long ago. Thanks for
looking at the report again, and feel free to close it.

Thanks for checking; I'm closing this report, then.
