Bug Description

Ubuntu 20.04.1 LTS

xorg:
  Instalado: 1:7.7+19ubuntu14
  Candidato: 1:7.7+19ubuntu14
  Tabela de versão:
 *** 1:7.7+19ubuntu14 500

        100 /var/lib/dpkg/status

Sometimes when I lock the screen or suspend the computer (I'm not sure if both or just lock) and after I log in to my user again, a window asking for the administrator password appears. This window is located in the upper left corner of the screen and is not clickable. I try to enter the password or cancel it but it is impossible, it is as if after the screen lock that window would get stuck ...

Result: if I can use the computer normally, I cannot remove the window, which occupies a significant part of the screen. Sometimes the situation gets worse and everything starts to stall. In such cases, I can only move the mouse, without being able to interact. Everything is stuck and never comes back. I can only fix this problem by restarting the computer.
