Description Sven Gothel 2019-12-06 08:39:58 CET
The wait loop uses XPeekEvent(dpy, &e),
which can block indefinite if queue is empty.

Replace with timeout only _and_ only wait on CreateWindow0(..)
not when queried via X11Display dispatch loop on events 
when it is assumed the information has been propagated already.
