Welcome to X11 where writing your own window manager is not easy.

I don't know which docs you looked at so far, but you aren't following ICCCM
section 4.1.7 "Input Focus"[0]. Your code assumes the "Passive" input model and
mis-handles all other input models. GTK is using the "Locally active" input model.

And while you are at it, also read the rest of ICCCM (perhaps except for the
selection, session management and colormap stuff).

Cheers,
Uli
