I have upgrade my ubuntu Ps to version 18.04. Now I can work on my PC but sometime I see that all my windows content become black (Internet Firefox, Terminal ect). I can close and reopen Firefox or other app but I cannot see the content.
Can somebody help me?

Glance at Settings Power choices (click on top right topbar icon, and click on the lower left icon to get the menu)
You can also run 'journalctl -b' into a terminal to find errors (red lines)
