Created attachment 1890961 [details] Video showing how the Tab key is used by gnome-text-editor and doesn’t reach the event processing of the input method - gnome-text-editor-42.2-1.fc36.x86_64 - Gnome Wayland or Gnome Xorg session - GTK_IM_MDOULE=ibus set in the environment - Start gnome-text-editor - Try to use any ibus input method, for example ibus-anthy as shown in the attached video - When using ibus-anthy, type “a” to get a hiragana “あ” - Type space to convert to kanji, the preedit shows “唖” (or another kanji with that pronunciation) - Type space again to open the candidate list and show the second candidate - Type Tab to select the next (3rd) candidate) => Now, instead of selecting the first candidate, the preedit and the candidate list move one tabulator width to the right. The input method does not see the Tab key event at all. When I use ibus-typing-booster instead of ibus-anthy, increase the debug level to 3 in the setup tool, and check the debug log like this: [mfabian@fedora ~]$ tail -F .local/share/ibus-typing-booster/debug.log | grep process_key_event I see nothing in the debug log when Tab is pressed, i.e. the key event doesn’t reach the input method. See attached video.
When the wayland input is used instead of the GTK4 input module, this problem does not occur. I.e. when using a Gnome Wayland session and starting gnome-text-editor like this: env -u GTK_IM_MODULE gnome-text-editor then the Tab key event is correctly processed by the event processing of the input method.
This message is a reminder that Fedora Linux 36 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 36 on 2023-05-16.

Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 36 is end of life.

Sorry for the late response. I checked the attached video with my mobile phone and report my thoughts to the upstream.
Yes, the problem is unchanged in f38. I also just tested it again.
There is a similar problem in kde now as well. Should the /etc/X11/xinput.d/ibus script be changed to not set QT_IM_MODULE or GTK_IM_MODULE when running under Wayland?

If you use GNOME Wayland, you should unset GTK_IM_MODULE and gnome-settings-daemon will set GTK_IM_MODULE=wayland and it works. If you use Plasma Wayland, IBus did not support the Wayland protocol in Fedora 28 but now works with systemsettings5 and unset GTK_IM_MODULE in Fedora39.
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
