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

This is definitely a Zoom problem. Never had it before. None of may settings changed. Yet today, me and all my people in the Zoom session have this freaking vignetting, regardless of the devices used.
