Brightness darkens from Window to Full Screen

Mac Technical Support
An interesting issue.

I have my brightness set to max (or close to it). When I move to window mode into full screen mode (cmd+m) the brightness is reduced to very dark. I have to go back into the Options menu to fix it. The thing is the brightness slider is still set to max brightness, but I need to !@#$le the slider for it to change the brightness to where I want it.

Has this been discussed?

We're aware of this bug (Gamma settings will not stick if you change the resolution).

This is something that has been escalated to Apple, as this is a bug that cannot be fixed on our end.
i have the same bug and don't use mac.
You will need to post in the bug forums for PC/Windows, as this bug was specific for Mac:
You should not escalate this to Apple, since it is your end. I am a Win7 guy, and this happens. Even when you alt tab and then tab back in it resets to dark. Fix it, and don't look to blame others.
That is a different issue for Windows users, as this was happening due to a Mac specific bug. This is why I mentioned that if you're on Windows, please post in the correct forum.
