I have a found several issues when importing SVG files found on Wikipedia to CorelDRAW X7. Whenever I import one, there are many artifacts or glitches.
Examples are: Map of the German Empire within Europe, circa 1914 where the German Empire is missing, and UK is moved southwards
Coat of arms of the Lands of the Holy Hungarian Crown where several elements expand past the image, even pas the visible field.
On their own the SVGs are rendered correctly in Internet Explorer or even in the online SVG Editor.
I look forward as to what may be the cause and the solution to my problem.
