Hi, I am currently creating a curses application that is updated independently of user input. Think of something like `top`. I realized that the process is using the same amount of CPU whether it is currently visible or not. That bothers me. I would prefer if my app got notified when its visibility changes so it can stop rendering (I think this is called culling).
For this to work it would need to be supported in several places: - Window managers could set _NET_WM_STATE_HIDDEN - Terminal emulators and multiplexers could set the terminal size to 0,0 - Applications need to actually use that information The only project I could find that seems to do something like this is mutter. So I am wondering: Is this even worth the effort? Have I missed any prior art? thanks tobias
