This question already has an answer here:

In Should I use fix-cm? the issue came up of strange output from Latin Modern. Here is an MWE to get this issue:

\documentclass[11pt]{article}
\usepackage{lmodern}
\begin{document}
TRUE

FALSE
\end{document}

has output as on the left of this image. Commenting out \usepackage{lmodern} produces output as on the right of this image. This is compiled with pdflatex in TeX Live 2012 and viewed with Adobe Reader 10.1.5 on Mac OS X.

Goofy LM, nice CM

Here is the result of \listfiles:

 *File List*
 article.cls    2007/10/19 v1.4h Standard LaTeX document class
  size11.clo    2007/10/19 v1.4h Standard LaTeX file (size option)
 lmodern.sty    2009/10/30 v1.6 Latin Modern Fonts
  ot1lmr.fd    2009/10/30 v1.6 Font defs for Latin Modern
 ***********

Many sources around the web (Wikipedia, this answer) say that the hinting in Latin Modern is not the best. On the other hand, the default Computer Modern in TeX Live is apparently not actually Metafont, but the Postscript Type 1 conversion by Bluesky, which the same sources say is the highest-quality vector conversion of CM. Is this accurate?

Xavier provided this pdf which demonstrates the issue; it renders correctly on some systems and not on others. In Adobe Reader 10.1.5 it looks like this.

CM Serif, LM Serif, CM Sans, LM Sans

    It seems a rendering problem. – egreg Feb 15 '13 at 21:36
  • I have experienced the same some time ago. It turned out that it only showed up on the screen and for certain zoom levels so I came to the same conclusion as egreg, that it would be some rendering issue. – Benedikt Bauer Feb 15 '13 at 21:53

    I can't reproduce your issue either. Please post a pdf file with the issue if you want me to check how it renders on my computer. Here is my test file, which renders perfectly on OSX with Preview and on Linux with Evince. – Xavier Feb 15 '13 at 23:22
  • @Xavier, your test file reproduces the issue for me in Adobe Reader. I'll add it to the question, if you don't mind. – Kundor Feb 16 '13 at 0:06
