Comment 39 for bug 339902

SVN commit 961177 by lunakl:

// We actually have to check the current stacking order. When an override-redirect
// window is shown or raised, it can get above the screensaver window and there's not
// much to do to prevent it (only the compositing manager can prevent that). This
// is detected by the screenlocker and handled here, but the contents of the window
// may remain visible, since some screensavers don't react to Expose events and
// don't repaint as necessary. Therefore, if a window is detected above any of the windows
// related to screenlocking, I don't see any better possibility than to completely
// erase the screenlocker window.
