Before the addition of the glare slider, media players would outright ignore light sources, displaying a pure signal.
While you can turn the “glare” slider to 0, you will still see light sources on top of whatever is playing. It’s very annoying, especially if you set up a viewing area within proximity of a disco/party ball.
I would really like an option to make a specific media player display like how it used to, without any sort of interference or influence from lights.
