Still, isn't this bizarre? Over the last couple of decades using Windows and macOS across many machines, I've encountered one time I had to mess with settings like this. That's the time I temporarily disabled hw accel in chrome so I could screenshare and watch a show with someone.

Would be appropriate to have true/false/auto instead of auto==true though, so auto wouldn't use it unless it confirmed to be working.
