"It did something really hacky. Basically when you minimized a window the core would store a thumbnail of what the window looked like before it minimized. It was not live."
That's not a bad idea, I think it's still better than showing just an icon.
You could also try having it remember which windows are minimized, then maximize all the windows, grab the thumbnails then minimize them again.
