1.52: Screenies now "none more black"

[KevinTMC]

Screenshots had worked just fine for me before; but I just tried taking some with version 1.52 (though the game in question is one I had started and completed under 1.09; don't know if that matters), and the resulting files in my Screenshots folder reminded me of a line from This Is Spinal Tap:

Nigel Tufnel: It's like, how much more black could this be? and the answer is none. None more black.

I'm attaching one of them just for kicks.

Anyone else experiencing this problem?
