Compile with gcc -I/usr/include/freetype2 -I/usr/include/cairo
cairo_xlib_simple.c  -lcairo -lX11 -lfreetype

Certain fonts/sizes get rendered incorrectly on certain distributions of Linux.
This mostly happens when rendering PDFs that were generated using LaTeX in a
browser using pdf.js.

I have extracted and attached the font from a PDF file with a rendering error
(as converted to OpenType using pdf.js). I have attached a small test program
that demonstrates the error using that font.

Distributions that seem to be affected:
* Most versions of Ubuntu/Debian
* Arch Linux with infinality-patched freetype/fontconfig/cairo

This seems to be a long-standing bug across many versions of various software.
Firefox bug report: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1200077">https://bugzilla.mozilla.org/show_bug.cgi?id=1200077</a>
pdf.js bug report: <a href="https://github.com/mozilla/pdf.js/issues/2594">https://github.com/mozilla/pdf.js/issues/2594</a>

In the next few comments I will attach screenshots of renderings including
version information.</pre>
