Hello,

I use texlive 2011.
After updating beamer from r25977 to r26288 (final release revision), I
noticed a problem in the rendering when using shadow and transparency.
Using evince, acroread or xpdf, I can see blocks over the covered ones.

Here a simple example, you can try with the 2 different revisions :

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{beamer}

\usepackage[T1]{fontenc}

\usecolortheme{orchid}
\useinnertheme[shadow=true]{rounded}
\setbeamercovered{transparent=20}

\begin{document}
\begin{frame}
  \frametitle{Problem with transparency and shadow}
  \pause
  \begin{block}{Bad display}
    Covered blocks are badly displayed...
  \end{block}
  \pause
  \begin{block}{When}
    Tested revision 26288 \\
    Last working revision : 25977
  \end{block}
\end{frame}
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%

Is it a bug or did I make something weird ?
It has always been working before.
