x-window-property seems to return nil for most properties.

(x-window-property "WM_HINTS")  -> returns non-nil

(x-window-property "WM_NAME") -> returns nil even though the property is
set (and displayed by xprop)

(x-window-property "_NET_WM_STATE") -> returns nil even though property is
set

In fact I haven't found any property I can read other than WM_HINTS.

I know this worked with previous version of Emacs.
