Video in browser goes black when screen mirroring is enabled on MacBook Pro

Both my iPad and MacBook M1 are running the latest OS. I've tried shutting the devices down and starting them back up, different browsers, and disabling all browser extensions. In settings, I've added and removed the browsers in "Screen System Audio Recording."


In all cases, as soon as I select Screen Mirroring, the video goes black in my browsers and on the screen I'm mirroring to. The audio mirrors fine. I've tried mirroring from both my devices to my TV and from my iPad to my MacBook. In all cases, the video goes black.


I can successfully screen mirror YouTube from my browser.


Is anyone else experiencing this? Was there something in the last update that caused this? Google is telling me nothing.

in general, to play content that is copy protected, EVERY display you could be putting that content up on MUST has HDCP High Bandwidth Content Protection featured as part of its inherent abilities.


Pay-TV services may have ADDITIONAL restrictions, and may not allow a second display at all.


Mac screen mirroring sends the Exact same data to each display, at exactly the same refresh rate, so you can not just blank one of the two displays involved.
