I don't. Of course I can't claim I tested this thoroughly, but no app
I typically use to write text displays stt similar.

My bet is that there are various APIs which could be used and this is
behaviour of some API emacs uses (at least in this build and in this
environment). I didn't see this popup „before problem started” (on
older Ubuntu) – then IIRC emacs composition worked silently, character
appeared only once fully entered.
