So, this problem only occurs when I don't log in, although I don't think it has anything to do with logging in. Some time ago, it started to display a text interface instead of the GUI. I'm pretty sure that it is a setting somewhere. I have looked long and hard at the settings, but don't see how to tweak it back. When I use an incognito window, the GUI works fine. I'm using Google Chrome as my browser. But, other browsers like Edge display the GUI just fine.
So, I would say that the bug here is that when a user inadvertently hits a key to change from GUI to text, there should be an easy way to change it back.
