Public bug reported: Hello, So I opened up the printer application on Ubuntu 18.04 (I don't use 18.04's default Desktop Environment on 18.04, I use Unity) and right-clicked on the a printer's queue, then right-clicked on the job, then I switched Wi-Fi networks (since it was trying to find a non-existent printer on Verizon's phone network instead of my home Wi-Fi network). Once it switched networks and figured itself and printed the job, the job disappeared, but the menu that was created as a cause of my right-clicking never went away. Literally everything in the desktop environment froze except for the mouse pointer, and I was able to hold down the SUPER key to show the shortcuts, but that was it. I could not click out, SUPER + L, CTRL + ALT + DEL all did not work. The only thing I was able to do was use CTRL + ALT + F3 to get into a terminal window. Once I got into the terminal, I did a: sudo ps aux |grep printer sudo kill -9 PID_of_printer_app
and was able to actually get my desktop environment working again.
