I built slock from 1.4, with the same desktop-revealing result. This is
on Xorg 1.16.4, which supports RandR 1.4.

I merged my patch into 1.4; it fixes the issue.

The RandR protocol documentation at
indicates under 'RRScreenChangeNotify' (just before section 8.1):

  Note that the sizes in this event reflect the new SCREENSIZE and
        thus will appear rotated by the 'rotation' parameter from the sizes
        of the screen itself. In other words, when rotation is 90 or 270,
        widthInPixels in this event will be the same as the height value
        from a ConfigureNotify that reflects the same size change. This
        will probably confuse developers.

I suspect that it's only accidentally working for some folks with
portrait screens.
