 	Unredirect all windows if a full-screen opaque window is detected, to maximize performance for full-screen windows. Known to cause flickering when redirecting/unredirecting windows. *--paint-on-overlay* may make the flickering less obvious.
 
+*--unredir-if-possible-delay* 'MILLISECONDS'::
+	Delay before unredirecting the window, in milliseconds. Defaults to 0.

 *--shadow-exclude* 'CONDITION'::
 	Specify a list of conditions of windows that should have no shadow.
