> That's caused by hardware acceleration .. Eh, no, this is because of DRM. The DRM that browsers now offer (wtf) allows browser applications to black out themselves if they detect things like screen recording. Not sure exactly how the implementation works (as DRM is generally a black box, on purpose), but it definitely is on purpose and not really related to hardware acceleration. The API Zoom is using for screen sharing is probably the same API you'd use to record the screen, so when Netflix detects that, they chose to black out the content.
