If you want to experience the difference, try to run your apps on
XDirectFB (http://directfb.org/xdirectfb.xml). It uses a
double-buffered window stack and thus doesn't need to send expose
events to windows that become unobscured. This makes a huge difference
when moving windows around and if your gfx hardware is supported by
DirectFB, it doesn't even cause any noticeable CPU load (if your gfx
hardware supports alpha blended blits, this holds true for translucent
windows as well).
