Unwanted "Vignette" effect I can't turn off

[ElevenMM]

I am surprised no one is talking about this because I see it everywhere. Several YouTube channels that use Zoom are having it. Zoom seems to be applying a sort of vignette effect around my face, darkening everything except my face. But when I raise my hands it sees my hands and brightens those as well. It causes these "blobs" of brightness throughout the image, and it's constantly moving. If I shift in my seat, half of my shirt will turn bright, while the other half will stay dark, and it will flutter and move constantly. It's especially infuriating because I go to great lengths to use professional cameras and lighting to get it right. I've tried every setting I can find, and see no way to turn this off. (It's not the "low light" setting) 

Has anyone found a fix for this? Is no one else bothered by it? It seems so unprofessional and janky. It's like a bad green-screen effect. Zoom, please give us the ability to turn this off!!

I do Zoom meetings all the time with professional PTZ cameras and never see this effect. You have most likely engaged a virtual background effect. check settings > background & effects

I have this issue, too, and it is frustrating that I can't turn this effect off.

I broadcast my video through OBS virtual camera and have overlays I use to interact with my audience in meetings and webinars.  However, they are now blurred in the zoom window.

I do not have any backgrounds or effects activated in Zoom
