bug#64300: 28.2; Can no longer input some tokens.

[Christian Brolin <cbrolin@gmail.com>]

Hi, sorry for late reply.

I'm currently using:
GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.37, 
cairo version 1.16.0)
  of 2023-03-16, modified by Debian

I don't know how to find out my previous version, but since I accept 
updates regularly, I guess it was the latest Debian build before Jun 26.

The problem still persist, but now I found out, only when I start Emacs 
from the main menu, not when I start it from a terminal, so maybe some 
problem with the environment. I tried to add LANG=C.UTF-8 to the menu 
entry which helped! So this is no longer an issue for me. But I still 
get the gray Pop-up somewhere on the screen when I press a modifier, 
e.g. ~ until I press the second key. I don't remember to have seen this 
before, is this a new feature? And if so, maybe it is related to this 
issue. But the important thing is that I now can use Emacs again.

Thanks for your efforts.
