Windows 11 VM was working fine until today. When I go into the  VM via VNC the log-in page is fine. I enter my Win 11 pin and the machine logs me in but as soon as I get to the desktop the screen starts flashing on and off and I am unable to use the mouse or keyboard. I can get the Task Manager to run by sending a ctl-alt-del through the VNC console but can't do much else. The VM is running fine as I have some background apps running for a webcam.  Using the virtual driver in Unraid for the VM.  Tried GPU pass through with the problem. Unraid 7.0.1. Any thoughts?

If nothing changed on Unraid then it's probably a Windows update/change.

• Do you have any backups on the VM that you can restore?
• You said that the issue still happened when you passed through a GPU? Any display problem differences at all?
• Can you RDP to the VM to see if it still happens?
• Did you try to change any of the GPU options on the VM in Unraid?

Update: I ended up restoring the Windows VM via Windows restore and it solved the problem with the video. I am still using the virtual video driver. I think the problem might have been related to a recent motherboard upgrade. I am currently having some issues with a Linux VM possibly related to the motherboard upgrade. The Linux VM runs fine but after logging in and out after several times, I try to log in and get a blank screen except for the Linux cursor. There is no response from the keyboard, but I can move the mouse cursor around. A restart of the VM restores functionality but only for a few logins then the same issue resurfaces. I will be trying some different settings in the VM config and see if it will resolve.
