+		Item nodes can have a &quot;background&quot; property, set to &quot;true&quot;
+		or &quot;false&quot; (not setting this property is equivalent to &quot;false&quot;), as follow :
+
+<screen>
+&lt;item type=&quot;rect&quot; background=&quot;true&quot;&gt;
+    &lt;normal file="background.svg"/&gt;
+    &lt;pos x=&quot;0&quot; y=&quot;0&quot; width=&quot;100%&quot; height=&quot;-75&quot;/&gt;
+&lt;/item&gt;
+</screen>
+
+		When this property is set on item nodes, background is applied to root window when greeter
+		exits after login, reducing screen flickering during login process. If no item node have &quot;background&quot;
+		property set, background is not modified when greeter exits.
