This last week, I was delighted to find that background blur started working in Zoom on ubuntu 20.04 without a green screen. No joke: I was waiting over two years for this feature to make it from Windows. I was happily able to host a couple of meetings using it. Unfortunately, after a reboot, I am getting the same bug as a few others have found: having background blur enabled either gives a black screen when you start a meeting, or will freeze your camera image if you enable it after entering a meeting.
Hello, I have just switched from windows to linux and I work remotely so I need Zoom, and here I found how badly it has been managed as compared to windows, and this virtual background option is necessary for people like me who works remotely.
