If my cheap laptop lcd isn't lying, there's a slight grey gradient on the side windows. It might be a bug. Or maybe your windows aren't 100% transparent?

If I'm right equilibrium is about those refractive objects that shouldn't be solid white on alpha channel..?

Strangely, in the last build, alpha of refraction at all gray.
I think the mode "Alpha Channel -> Always Solid" does not work.

maybe i wrong, but i think refractive area must be white color
P.S. render PT+PT, illumination - standart (corona sun +corona sky), corona alpha 3(not daily build)

It depends on the parameter, but it's not work

I've fixed some bugs with alpha, nevertheless:
- glass materials' alpha is not pure black, because those have also reflection
- when environment is visible through glass, the alpha should come out black, as it is on the columns in your example. Unless you change alpha mode to solid.
