You can accomplish this with straight X11, no need for the DE to be aware of it.

  I don't think that's so trivial in a composited world. IIRC once upon a time you could easily get a viewable state from the X server for windows, but with compositing xorg made it basically always true.

    In wayland it's very simple. You would use surface frame callbacks, which aren't supposed to trigger when the window is fully obscured, minimized, or off-screen on another desktop. This mechanism never seems to have made it back into composited X.
