I've got a Microsoft Life Cam plugged into a Dell Optiplex 5080 - with Windows 10 Education 20H2 and the latest version of Teams installed. The camera blinks my video feed alot during Teams meetings and Zoom meetings. The Life Camera cinema driver date is 1/29/21 version 10.0.19041.789. The Optiplex 5080 has an Intel UHD Graphics 630 driver (which I think this driver and maybe the 620) have caused issues with virtual backgrounds in Zoom. The UHD 630 driver version is 18.104.22.16816 and the date is 2/18/2021. I'm using the latest version of Zoom 5.5.4.
