RemoteFX Display problems on Windows 8.1 VM but not on Windows 7 VM running on Hyper-V VDI Server 2012R2 RRS feed

  • Question

  • After many, many, hours of wading through and eliminating potential variables the issue has been narrowed down to being present with a Windows 8.1 VM and not on Windows 7 VM.

    The problem is with glitchy display issues (Random Pixellation, Fuzzy Screen areas, Entire Screen filled with random shapes/colors etc.).  

    This is a Server 2012 R2 environment it is running Hyper-V Remote Desktop Virtualization Host.

    1. An Nvidia Quadro K2200 adapter has been enabled for RemoteFX and passed through.
    2. Also have tried Nvidia Grid K2 adapter. Both adapters use same driver set and multiple driver versions have been tested.
    3. Two Generation 1 VM's have been created.  One for WIndows 8.1, One for Windows 7.  All updates installed.
    4. Each VM uses the same set of Hyper-V resources, Virtual Switch etc.  (The settings for each VM are the same).
    5. With RemoteFX disabled on each VM the issue is not present on either VM.
    6. With RemoteFX enabled on each VM the issue is present on the Windows 8.1 VM and not the Windows 7 VM.
    7. There is no difference if only one VM at a time is enabled and running.  (Not GPU load related)

    All of the preliminary issues have been eliminated (Correct client OS version, DirectX 11.1 GPU etc.)
