Created attachment 1863975 [details] Screenshot showing the wrong position of the candidate list using ibus-anthy - Fedora-Workstation-Live-x86_64-36-20220216.n.0.iso installed in qemu-kvm - all current updates installed. - Gnome (Xorg) desktop - gnome-text-editor-42~alpha2-1.fc36.x86_64 When typing into gnome-text-editor with any ibus input method, the candidate list is far below the cursor position. Seems to be always far below the gnome-text-editor window, if the lower edge of the gnome-text-editor window is low enough, the candidate list is not visible anymore. See attached screenshot.

Created attachment 1864038 [details] Screenshot showing the wrong position of the candidate list using ibus-anthy in gtk4-demo The problem is reproducible in gtk4-demos as well. So it is probably a gtk4 problem and not specific to gnome-text-editor.
I can reproduce this issue with Fedora-Workstation-Live-x86_64-36-20220307.n.0.iso image running on bare metal: ibus-1.5.25-13.fc36 ibus-gtk4-1.5.25-13.fc36 gtk4-4.6.1-2.fc36 The issue seems to be slightly different for gtk4-demo-application and gnome-text-edit/gnome-control-center. It also depends on Wayland or Xorg environment, although Wayland plus GTK_IM_MODULE=ibus and GDK_BACKEND=x11 environment variables behaves the same as Xorg. gtk4-demo-application, Wayland: The candidate character panel is to the upper left of where it should be and covers the cursor and the text. gnome-text-edit/gnome-control-center, Wayland: Similar to above. In addition, the IME can't be switched on or off by pressing the Shift key. gtk4-demo-application, Xorg or Wayland plus env vars: The candidate character panel is far away to the lower right of where it should be and sometimes outside the window. gnome-text-edit/gnome-control-center, Xorg or Wayland plus env vars: The candidate character panel does not show up at all, although the text input actually works if I choose the word by pressing number keys. Shift key on/off switch also works.
