I am having the same problem. A few days ago I upgraded my computer from Ubuntu 19.10 to 20.04. Normally I was starting the MySql server manually. It started working automatically with the update. When I put the computer to sleep mode and turn it back on, the authentication window for the MySql server is opening at the upper left corner and is not closing in any way. The thing that catches my attention here is that when I click on the window that does not close, the application under the window detects the click. However, the cancel button and the password text box is not performing their functions even though they sense the clicks correctly. Notice: Restarting the shell closes the window.
