I suspect Gnome fades GUI apps to gray when they go too long without 
checking for user input (from the X11 event queue), and/or don't update 
the GUI.  There are many reasons an app may take a while to check for 
input or do an update.

I don't know if any of the other Ubuntu window managers (KDE, XFCE, 
etc.) have this behavior.  If they do, then it could be an X11 setting 
that Ubuntu configures, rather than being WM-specific.
