HDX3DPro Screen refresh issue, black bars


Tim Wolf1709161047

Question

Hi community,

 

I've came across an issue with HDX3DPro on Windows 10. 

During a session the screen does not refresh properly. In order to refresh the whole screen I have to drag the app windows around or switch between windowed mode and full screen.

The issue happen on all clients and must be related to the worker. It only occurs if the GPU is used to encode the session, "For entire Screen" rendering.

System resources are relaxed, no high CPU/RAM/Disk/Network (RTT/Latency)

Worker is connected through Citrix Cloud Gateway Service with Rendezvous v2 protocol via UDP (EDT).

 

Specs

CPU Intel 6246R @ 3.4 GHz

16GB Memory

Nvidia P40-6Q (Driver 452.57) and corresponding GRID driver

-  I am aware that the GPU driver is outdated but we have an older farm running using the same driver and hardware without that issue.

Windows 10 21H2

VDA 2206

Workspace App 22.7.0.24 (2207) and older

H264 or H265 codec

Any idea folks?

Regards

Tim

I have seen similar when one of the following conditions had been met.

 

1. Nvidia vgpu licensing wasn't allocated to session.

2. Client Workstation App was outdated.

3. Client was connecting to cloud.com location with DWC enabled, but were using workspace app instead of browser for connection.

4. Graphics memory was set to 65k instead of 4000k.

Thank you Jeff, unfortunately none of this fixed it. ?

As soon as I enable HDX3DPro these Black bars appear.

Is this happening from all endpoints?

 

Have you tried updating the gpu drivers on the endpoint?

yeah multiple endpoints, different devices. all the same.

Must be VDA/GRID related but I can't update the vGPU/GRID drivers at the moment without impacting dozens of other VDIs that are running an older OS build without issues.

 

Just updated the Windows 10 GPU Driver to the latest 453.64, but same problem.

Will try to update the GRID driver as well...
