Hi. I can confirm that launching with XMODIFIERS=@im=none GTK_IM_MODULE=none emacs -Q seems to be getting rid of the annoying popup.
However, AFAIU, xterm exhibits the same behaviour than emacs-gtk. Without those variables set, the popup appears whenever I compose an accent with ^, and stays there in the middle of the display. Launching with XMODIFIERS=@im=none GTK_IM_MODULE=none xterm gits rid of it and accents work as expected.
Hope this helps, Le 30/11/2025 à 16:55, Alexandre Lymberopoulos a écrit :
Dear all, Running emacs setting export XMODIFIERS=@im=none export GTK_IM_MODULE=none deactivates the preedit window for the accent. So it seems that there is something in the interaction between emacs and ibus, since this phenomena happens only in emacs. This preedit "window" works fine in xterm in both contexts (with or without those variables set). Best, Alexandre
