Windows, such as the notifications in Chromium and Steam, can bypass the lock screen in xscreensaver. To quote the help found on the FAQ at the Xscreensaver website,
"you should be mapping windows with XRestackWindows instead of XRaiseWindow, to ensure that managed windows always appear below override-redirect windows."

    From the same link:
    "It is also possible that the application that is popping up the window is doing so using an override-redirect window of its own. (This is currently the case with GTK_WINDOW_POPUP style dialogs.) In that case, it is impossible for either xscreensaver or the window manager to prevent those windows from popping up, since override-redirect windows, by definition, bypass the window manager."

    I might check later how Fluxbox handles it, but I bet Chromium's case is unsolvable. I don't know about Steam, though.
