How severely does this bug affect you?: 

●●●● — It prevents me from using Vuo at all.

Steps causing the bug to occur: 

I don't have an M1 myself. I've had two reports of 3-5 second video lag with my Vuo-made application, when running on M1 Macs. Given the performance of these machines, I can only guess something else is going on.

The app takes a video feed, and outputs a syphon feed.

Other notes: 

Unfortunately, this makes my app unusable on M1 Macs.
