I've tried but only found this one:

  bug#52677: 29.0.50; make-frame-visible/invisible too slow when use --with-pgtk

Anyhow, I think being able to toggle a frame's visibility state on/off
only ten times a second isn't so horrible slow.  Of course, it depends
on use-case.  But for show-paren where there's `show-paren-delay' anyhow
it doesn't really matter from my POV.

FWIW, I don't have posframe installed but tried this benchmark which is
quite similar:

  (benchmark 10
             '(show-paren--show-context-in-child-frame "foobar"))
  ;Elapsed time: 1.178163s (0.047553s in 3 GCs)
