To reduce probable unnecessary work, would tracking VisibilityNotify
events help?


BTW, as most WMs also deal with input focus management, and as most
WMs wrongly ignore OverrideRedirect windows in practise, you have to
forcefully 'recover' focus too on each FocusOut event... the same
you raise the window (assuming your client expects input of course).

Just curious, how could a WM enforce some policy in that regard at
all, say at Xlib level or otherwise (aside of the question if it
should do anything in this respect at all)?  Isn't it much like the
same as with 'focus'?
