TIP 1 – Facing black entries while scrolling in Windows 10 Immersive Control Panel (Apps & Devices)?
Maybe this is the reason why…
If you are using VMware Horizon Agent 7.10 (and below), VMware Blast protocol to connect to Windows 10 (v1803) VDI session and have a NVIDIA Grid vGPU card in my case Tesla T4 (1b & 1q profile with 9.1 Windows Driver version), then probably your refresh rate is set to 20Hz, while 60Hz is available. I’ve tried several ways to capture the refresh rate with VMware Dynamic Environment Manager (DEM) or couldn’t find a way to force it via the registry. All with no luck. After creating a support ticket at VMware, they told me this is a known issue and I should try to use the Horizon 7.11 Agent. After creating a new Windows 10 VDI Test Pool, the refresh rate is set to 60Hz and the black entries while scrolling in the Windows 10 Immersive Control Panel in the Apps section & Devices (adding printers or scanners) section. It is a bug in lower versions of the Horizon Agent in combination with newer NVIDIA Grid vGPU Windows drivers.
