If input focus is set by the window manager, it is not necessary to send WM_TAKE_FOCUS because it has already taken focus. http://tronche.com/gui/x/icccm/sec-4.html#s-4.1.7 > The goal is to support window managers that want to assign the input > focus to a top-level window in such a way that the top-level window > either can assign it to one of its subwindows or can decline the offer > of the focus.

Both setting input focus and sending WM_TAKE_FOCUS is effectively setting focus on the window twice which is certainly against the spirit of the spec, if not the letter. fixes #1167
