Blinking Red Screen on Login

Brass Contributor

Having an issue with some VMs in an AVD Pool where, on login (via the Windows Desktop App or via straight RDP) the login begins but instead of getting a desktop, you get either a screen that blinks red the entire time or you get to the desktop but you cant use it as the screen will blink red every 1-2 seconds.  The only way I have found to fix it is by rebooting the VM.  This doesnt help when the issue occurs and the VM is in production being used by many users.  The issue will cause other users to not be able to login to the pool as well as the broker is trying to put them on the affected VM.


Any clue as to what is happening here?  I've looked in the Main Event Logs and dont see anything odd at the time of the issues.


Thanks, your help is greatly appreciated.
