Welcome Screen After Screensaver CFP

New to this beta no problem with previous beta.
I do not get the welcome screen after screen saver to log on just a blank screen, have to disable this option on my screen saver display.
Also switch user I know does not work but if you try then log back to the same user the same happens blank screen.

It now works after changing I receive several alerts (Login etc) and change back to log/welcome screen after screensaver.
Also had lock up problems after standby after two or three attempts at standby I received several alerts (DNS etc) after which I had no problems with standby.
This beta seems to be slow with it’s alert or none sometimes.
