Keyboard layout/language changing not working on login screen

[Lukas]

In Ubuntu 18.04 I have two keyboard layouts set, US QWERTY and BE AZERTY (the latter one being the original layout of the laptop keyboard). On the login screen I have the option of switching between language from the selection menu in the top right corner and I can also change it by using super+space. However, when changing the layout, it shows it is changed, but it does not actually change. The layout remains the first one, despite the drop-down menu showing otherwise.

This can be very problematic when one has to type the password to login, as it was for me, since my password contains a special symbol which is not present on the QWERTY layout. I managed to still log in using unicode input, but this may be a severe problem to users with less experience.

Reproducibility note:
The bug seems to be only reproducible if I set the US QWERTY layout as the default (i.e. not the actual layout of the laptop keyboard). If I set the the BE AZERTY layout as default, the switching works as it should.
