[texhax] could someone give me an explanation as to why fontsize fails with an overfull box

[David Carlisle]

As before \sloppy makes a reasonable setting of your second example

\documentclass{article}
%\documentclass[14pt]{extarticle}

%\usepackage{MinionPro}
%\usepackage{mathptmx}
\usepackage{libertine}
%\usepackage{fontspec}

%\setmainfont{MinionPro}

\setlength{\parindent}{9.94pt}

\showoutput
\begin{document}

%\fontsize{14.09}{14}\selectfont
%\fontsize{14.0908}{17}\selectfont
\fontsize{16.09}{17}\selectfont
\sloppy
The reason is that upon restarting the computer, there are also other programs
that start running on the background, among them Antivirus programs and
whatever other programs Windows deems necessary for the functionality of
the system.

\end{document}
