How do I close the redundant "authentication required" dialog visible in the corner?
The way to make this dialog appear is to...
- have a laptop monitor on the right and an external monitor on the left displaying a Firefox browser. This setup involves the HP Zbook on Ubuntu 20.04
- suspend
- press the power button and type in the authentication password
- see the illustrated authentication dialog on the left monitor and note that it partially obscures a browser window but in fact it is not actually preventing use of the browser. It is possible to activate the browser window and click play on the YouTube video
- observe that the authentication dialog cancel button is not functional and attempting to authenticate using a password and the authenticate button is also not working
