Trying this manually had exactly the desired outcome: CPU usage dropped to 0. Nice!

Even if there is little gain it might still make sense if the solution is simple. This feels like it could be simple, but I am not sure. Concrete steps: - dwm sets _NET_WM_STATE_HIDDEN on windows that are currently not displayed - st sends XON/XOFF when _NET_WM_STATE_HIDDEN is set Do you think this would be reasonable or are there potential issues I am missing? tobias
