Windows 1903 WDDM driver issue

This post was originally published on this site

Hello All,

We are in the process of upgrading our VDIs OS to Windows 1903. Our infra is using Horizon 7.12 and all agents and tools are upgraded to the latest versions.

During the pilot testing process, we find that the pools which are using RDP protocol to connect the VDIs are facing black screen issues and frequent disconnection with RDP 3334 protocol error.

Disabling the WDDM driver through group policy and using XDDM drives solves this issue. We are using static VDI(dedicated) deployment.

Any suggestions or anyone facing the same issues?
