Same code running on two servers, one is running on Tomcat on Debian and the other is Tomcat on Windows. They both have SansSerif font, but the Debian one text looks more stretched and wide than the Windows machine. The public PlantUML Server matches my Debian server. I think the Windows one looks better. Any idea what the issue might be?
