Need Help with AVD Pink Screen on GPU VMs

John Fowler 5

Hello Folks,

We are implementing AVD for GPU users.

They have been experiencing (at random times throughout the day), their screens turning pink and distorted (image attached). Unfortunately, there is not much documentation online for this specific issue and troubleshooting has been difficult. The user's current workaround is to close their AVD session and then reopen it (something not sustainable as a fix).

The GPU users are using Standard NV6ads A10 v5 & Standard NC8as T4 x3 personal machines.

Has anyone run into this issue before? Any guidance is appreciated.

We're having the same issue in AVD with multiple NV36ads_A10_v5 VMs. I've updated the drivers, confirmed extensions, etc. As long as AVC 444 is enabled on the session host then users will randomly experience certain screens with pink/green overlays until they close and re-open their remote desktop application. Disabling 444 on the local session host will resolve the issue, but then GPU acceleration and full frame encoding will not work which will pixelate videos online.

Hello John Fowler

Welcome to Microsoft Q&A Platform, thanks for posting your query here.Based on the details you have shared, it is mostly caused by issues with the GPU driver.
Please make sure that you are running the latest supported version and also make sure that MSRDC is updated.

Hope this helps.

Thanks, Vipullag. But we have done that already. The pink screens do not seem to have a discernible trigger. They will happen out of nowhere to one engineer and then the rest will have the same issue thereafter.

We recently tried this on a couple local systems to see if it makes a difference:

From the run command open gpedit.msc

Navigate to Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Connection Client

Double click the below setting located on the right-hand side: Do not allow hardware accelerated decoding

Set Do not allow hardware accelerated decoding to ENABLED

We have a set of users who have this applied.

Is this anything you are familiar with that might help solve the issue?

We have already done that.

We did just try this fix yesterday on about half of the users. So far, so good but not enough time to really determine if it fixes the issue.

Are you at all familiar with that?
