Users of input-methods upgrading from earlier versions of Fedora may need to install ibus-gtk3 or GTK3 versions of their GTK immodules if available, in order for input-methods to continue working normally on their desktop.
im-chooser (via imsettings) now allows to fully disable input-methods for users that do not need X locale compose support (using XIM): so Unicode input with Control+Shift+u works again in GTK applications by default when not using input-methods like ibus.
