Yes, this is true, but this has been that way all the time and was never intended to be different.
If you want to use transparency on Window you could try to use the experimental cairo backend for Windows.

I'm trying to shade part of a view by drawing a partially-transparent shade of black over it in my drawRect: method. This works fine in Cocoa and in GNUstep on Linux, but produces solid black on Windows. The code is basically like this:

NSBezierPath *shadePath = [NSBezierPath bezierPathWithRect:shadeRect];
[[NSColor colorWithCalibratedWhite:0.05 alpha:0.35] set];
[shadePath fill];
