Git commit f3452076a7e710e1d165ed3d759a2cb17bad1366 by David Edmundson, on

x11: Update XStacking order when adding override-redirect windows

Kwin uses it's own stacking order for managed windows and X11's stacking
order directly for unmanaged windows.

The X11 stacking order is updated only in resonse to
XCB_CONFIGURE_NOTIFY on the root window, but if this fires before the
window is mapped by kwin the window is not added to the unmanaged stack.

This can leave things out of sync when we have multiple fullscreen
unmanaged windows, which is the case of the lockscreen.
