on a fresh Ubuntu 20.04 installation, i'm currently facing the issue that i can't switch between two keyboard layouts with the shortcut super + space.
I use a Duck2 mini with QWERTY layout, ubuntu system language is English (US) and also the first (main) input source. After i switch to any other language using the shortcut, the indicator on the gnome bar and also the popup in the middle of the screen shows that the layout has switched, but i can't use the layout or any of the characters from the second language.
I found out that if i delete the second input source and "reinstall" / add it to my input sources, i can switch properly and use the layout.
Unfortunately i don't know what kind of output would be helpful durig the troubleshooting process, so feel free to let me know what you folks need.
Thank's in advance.
Regards
