Description

Magick::Image::display works only once

The second time a number of pointers in windows will be null:

ImageMagick/MagickCore/display.c

Line 14609 in 66ceff0

visual_info=windows->visual_info;

visual_info is initialized correctly only when the X subsystem is initialized, it is null on the subsequent calls.

Steps to Reproduce

Magick::Image im("50x50", "black");
im.display();
// close the window via the window manager
im.display();
