I'm making a window which captures a screen image then applies a filter to it for drawing effects (like the menus in the Dock). The problem I'm having is I can't be sure when anything in the screen changes underneath it changes so I don't know when to update the screen image.
Are there any notifications I could get that would tell me if screen pixels changed that were within a certain rect on screen? Thanks.
