--- Comment #19 from Jens Petersen petersen@redhat.com --- I think it also depends on where one opens from:
- from control-center: it shows the empty '?' window for me - from the Input Source menu: it showed a keyboard layout.
But I haven't tested thoroughly for many different examples (only with one layout and 2 IMEs (Japanese and Chinese) setup.
