CS4: I_WINDOW5 has bad color reproduction (dithered gradients).

[AdmiralCurtiss]

In PS4 CS4, the I_WINDOW5 texture was patched because they misspelled ACC as AGG (though even the fixed one has an overlooked instance of AGG...), but in the process they messed up either the color depth or the alpha channel; the unpatched texture looks a lot better than the patched one. The PC version uses the 'bad' patched texture.

Probably best to take the unpatched texture and manually fix the two instances of AGG.
