[Tex/LaTex] Warnings with beamer class and itemize

beamerfontsizesymbolswarnings

I'm getting the following annoying warnings:

LaTeX Font Warning: Font shape `OT1/cmss/m/n' in size <4> not available
(Font)              size <5> substituted on input line 16.

...
LaTeX Font Warning: Size substitutions with differences
(Font)              up to 1.0pt have occurred.

I tryed to reduce the a minimal working example as much as possible:

\documentclass{beamer}
\usepackage{textcomp}
\usetheme{Boadilla}
\useinnertheme{circles}
\useoutertheme[subsection=false]{miniframes}
\usecolortheme{seahorse}

\setbeamertemplate{navigation symbols}{}

\begin{document}

\begin{frame}
    \begin{itemize}
        \item bla
    \end{itemize}

\end{frame}


\end{document}

Any ideas how to resolve that?

Best Answer

To completely remove those warnings, you should

  1. load the textcomp package to provide the missing \textbullet symbol (as done in the edited version of your question);

  2. use a scalable font like lmodern to provide a font size of 4pt.

\documentclass{beamer}

\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{lmodern}

\usetheme{Boadilla}
\useinnertheme{circles}
\useoutertheme[subsection=false]{miniframes}
\usecolortheme{seahorse}
\setbeamertemplate{navigation symbols}{}

\begin{document}

\begin{frame}
  \begin{itemize}
    \item bla
  \end{itemize}
\end{frame}

\end{document}
