I also get a freeze with this recipe, "freeze" meaning no response to
normal keystrokes, incomplete screen redraw.  I'm attaching a
size-reduced screenshot.  I get out of that state by pressing C-g four
times.

When I connect to the Emacs in this state with gdb, I get the stacktrace
below.  It seems that make-frame-visible is waiting for some answer that
does not come from X11 or the display manager.

I am testing with Emacs from Git here, head of branch emacs-25, i3-wm
4.8, Debian GNU/Linux 8.5 (jessie), X.org 1.16.4.
