Teams backgrounds with View and PCoIP Zero Client

Hi,

i have a Windows 10 VM with 16 GB, 4 vCPU of a Xeon Silver 4110 CPU and via vDGA a Nvidia Tesla P4 GPU.

I'm using a Fujitsu Futro L620 PCoIP Zero Client, which has a Tera 2140 with 2 monitors at 2560x1600.

The Horizon View Agent is the latest and i have USB Passthrough enabled.

At the Zero Client i have a Microsoft LifeCam HD-3000 USB cam connected, this Webcam works without problems. I see the camera directly as a USB device and the driver for this is installed in the VM.

For using the speaker and microphone connectors of the Zero Client i have installed the Teradici audio drivers, this is working without problems too.

The only problem i have: I'm not able to activate my own backgrounds in Teams. I can only use background blur.

Is it possible that Teams disable that feature because i'm in a VDI session?

Or where can be the problem?

Is there something else i can optimize?

Kind regards

Stefan
