I wonder if they are using the netwm visibility state oddly? E will set
the netwm state to invisible if a window is iconified or when screen blanks and
set it back when it is uniconified or screen unblanks. Also if you switch
virtual desktops windows on other desktops get the hidden state set and
removed when they appear again. When does it freeze and stop rendering? what do
you do before that to make it happen?
ie you will see:
_NET_WM_STATE(ATOM) = _NET_WM_STATE_HIDDEN
if you use xprop on a window if its iconified, on a non-visible virtual desktop
or when screen blanking starts. that property will be deleted/removed when it is
uniconified or otherwise visible again.
