This applet allows you to <b>toggle the composite ON/OFF</b>.
The composite is what allows transparency on the desktop, but it can slow down your PC, especially during games.
<b>Click</b> on the icon to switch the composite ON/OFF. You can define a <b>shortcut</b> for this action.
The applet also lets you acces to some actions of the Window-Manager, from <b>middle-click and the menu</b>.
You can define in the configuration a Window-Manager that will provide the composite, and another as a fallback.
