Linux has always handled font scaling better than windows in my experience. Windows has a tradition/culture/tendency toward building user interfaces by positioning UI elements in absolute pixel coordinates. But linux UI toolkits put much more of an emphasis on automatic/scalable layout.

Font scaling works just fine on Linux. The problem is icons. Many Linux programs don't have icons for high resolution displays, so while menus and toolbars look fine, icons are unclickably small.
