hm, i just tested this on my macbook and the way it seems to work is certainly breaking live visuals, but at the same time does not protect people from being recorded: if i start an audio recording and then watch a film fullscreen, the orange dot does show, but then vanishes (while still recording the audio). not sure if this is intentional or a bug, but it would certainly render my computer unusable for quite some work i do. audiovisuals almost always are reactive to sound in one way or or another, so you do record the ambient audio for your video or installation be able to react to it.
