I've been noticing that my screen appeared to be dimming randomly (or at least it seemed random at first). I search the web and found tons of people complaining about the same behavior, and adjust their energy settings and ambient light settings, but none of it worked. Their Macs kept on occationally changing the screen brightness.

Idleness wasn't the issue: During my tests I was actively using the computer (and I'm plugged in)
Ambient Light: There was no change in ambient light, so it wasn't this either (and I disabled this setting and the behavior persisted).

However, what has changed is the contents of my screen. If I go to a website with really dark graphics, or go full screen on some movies, the screen brightness turns down. I can reproduce this 'dimming' effect consistently... and then I found this:

Apple has a patent that allows them to dim screens based on their contents. I am certain this is what is affecting our screen brightness. This is meant to be a power saving feature according to the patent, but it is SUPER annoying. What I can't figure out is how to turn this setting off...
