If you go VK, FB with Ubuntu or Windows that fonts will look different. Why is this happening?
This happens because most sites are configured in such a way that would use several fonts, in order, depending on what the user has the fonts installed. And/or are configured to use font family .
Resp., since different systems have different fonts from a set of "default" - they look too different. And it does not depend on "Windows/Linux", even in different versions of Windows or different Linux Ah - fonts can look very different.
If you want the fonts looked, for example, in Linux, the same as in Windows - install fonts in Linux from Windows.
Yet such behavior is sometimes associated with the parameter "default font" in the browser, respectively. in different systems this font for obvious reasons will be different, and in the absence of specifying a specific font on the website - the text will be rendered exactly in this font (which is "default").
