I haven't looked into detail but this doesn't seem to work for whole window opacity (set with `SetLayeredWindowAttributes( hwnd, 0, 255 * 70 / 100, LWA_ALPHA )`) or `UpdateLayeredWindow` per-pixel alpha either.

There's maybe something to do with `window_surface->alpha_mask != 0`, which also indicates per-pixel alpha, and should probably trigger usage of ARGB, but that doesn't seem to be enough.
