Fonts & Character Sets ⇒ beamer, lmodern and \dot

[pizzocaro]

Hi all.

I am writing a presentation with beamer where a lot of dotted y appears.

Code: Select all

$\dot{y}$

However while using the Latin Modern package, the dots are awfully placed.
See MWE:

Code: Select all

\documentclass[hyperref={pdfpagelabels=false}]{beamer}

\usepackage[english]{babel}

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

\usefonttheme{serif} 

\begin{document}
\begin{frame}
\[\dot{y} = \ddot{y} = \dddot{y}\]
\end{frame}
\end{document}

The problem happens only with beamer.
The problem is there also with sans-serif fonts (but it is more striking with the serif one).
The package amsmath does not help.
Removing lmodern solve the problem but I get font errors.

Do you have any suggestions? Thanks!

Marco
