I found the issue trying the examples of libXbgi library
(http://libxbgi.sourceforge.net), so I tried to create a STC adapting
the example discusses here:
https://user.xmission.com/~georgeps/documentation/tutorials/Xlib_Beginner.html
Anyway, the STC on Cygwin64 doesn't work if I add your suggestion,
...
XMapWindow(dis, win);
XSelectInput(dis, win, KeyPress);
XFlush(dis);
...

as I wrote, on OSX it works (there XQuartz is 2.7.7). For this reason I
flagged this to X-Cygwin list..

On which system? OSX?
