none at all. BypassWindowManagerHint just says it should be override redirect. 
That is a window manager will not manage it. Any window can go above it if it 
wants (X11 is not protected, any window can raise it as it wants, KWin and 
other window managers prevent that, though, but only for managed windows). The 
WindowStaysOnTopHint is completely useless as well as the FramelessWindowHint 
as both only apply for managed windows. Even if the WindowStaysOnTopHint 
doesn't say it should stay on top, but just that it's in the Keep Above layer 
of the window manager, which isn't the topmost layer.
