Hmmm, what version of GTK+ are you using?

        * gtk/gtkentry.c (gtk_entry_enter_text): Call
        gtk_entry_set_position_internal() that takes a
        new "reset_IM" parameter, so that we avoid the
        problem where committing text would reset the
        input method. (#74381, Kang Jeong-Hee)

Are you you using gtk_im_context_delete_surrounding ()? ... that's
the only way that can back and change what you have committed already..

Or are you simply doing partial commits?
