Xfree86 video buffering?

Recently I have noticed that after shutting down my machine or rebooting my X-windows will briefly flash an image of whatever I was doing when I rebooted the machine or logged out.

As an example if I was browsing porn at night in mozilla just before I clicked "K->Logout...->Reboot Computer" in KDE, the next morning when my Girlfriend turns my computer on she gets a quick 2 second shot of my porn just before the KDM login screen.

What causes this? Can it be prevented? I can certainly see sensitive data potentially being leaked via this quirk.
