Although Linux has come a long way in the 25 years since I started using it with Red Hat 5.2 or whatever, there are still those squirrelly things that means if you install X, it breaks Y, and even when X is removed, Y remains broken, and you just have to bypass it.
I borked my keyboard layout and it seemed the layout applet (the Japanese flag in my previous screenshot) and the full screen app dashboard I installed did not play nice. In the end, I had to remove both.
