It seems xim support in GTK3 is known to be buggy and GTK upstream say:
the recommended fix is not to use xim
https://gitlab.gnome.org/GNOME/gtk/-/issues/2560#note_757143
Support for xim has been removed completely in the development branch
which is leading to GTK4:
support for the xim input method has been removed in favor of IBus
