GZDoom overrides Windows brightness after closing

[Guest]

I'm using a dual-monitor setup and every time I close GZDoom it changes my system brightness, making everything very dark until I go back and reset my settings in Nvidia Control Panel.

Not only that, it also seems to affect other programs. For example, if I try to launch Counter-Strike: Global Offensive any time after closing GZDoom (and fixing my brightness settings), it will darken everything again whenever I launch the game or tab in, so alt-tabbing and fixing my NVCP settings then tabbing back in to CS:GO just darkens everything again. I have to restart Windows entirely to fix it.

I wonder if it wouldn't be possible to just map Gamma correction through shaders?

No, that'd result in gross reduction of color precision. The output is still limited to 8 bits and if you mess around with that you'll lose a significant part of it.
Normally GZDoom should reset this to its former value, it really looks like this is broken on multi-monitor setups.

Shouldn't a shader do the same thing as gamma correction code in software renderer? In other words I'm curios why color precision is lost.

duplicate report.
