Inconsistent size of a block causes 2 blocks to be misaligned

Question

I'm creating a presentation using beamer and I've detected a slight size inconsistency of a block located in a second column or minipage.

I want to align two blocks with the same amount of bullets and lines using columns or minipage (actually both produce the same result), but the title bar of right block is bigger than the left one. This causes the blocks to be slightly misaligned.

The theme I want to use is marburg, with the rose theme color.

Here I provide a picture showing the phenomenon and the MWE code.

\documentclass[serif]{beamer}

\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage[spanish]{babel}
\usepackage{mathpazo}
\linespread{1.05} 
\setbeamertemplate{navigation symbols}{}
 \usetheme[hideallsubsections,left,width=2cm]{Marburg}

\usecolortheme{rose}
 \setbeamercolor{titlelike}{bg=structure,fg=white}

\begin{document}
\section{Lorem Ipsum}

\begin{frame}
\begin{minipage}{0.45\textwidth}
    \begin{block}{\hfill Razones}

    \begin{itemize}
    \item Reducción del torque resistente. 
    \item Daños en la fuente original
    \end{itemize}
    \end{block}

\end{minipage}
\hfil
\begin{minipage}{0.45\textwidth}
    \begin{exampleblock}{\hfill Expectativa}
     \begin{itemize}
    \item Reducción de canales de alimentación.
    \item Tensión de alimentación estable.
    \end{itemize}
    \end{exampleblock}

\end{minipage}
\end{frame}

\end{document}

Any suggestions? Thanks in advance,

Answer 1

Add a \strut and the [t] option to the minipage:

or you can add a \vphatom{p} to the first block to get slightly tighter spacing:

Notes:

• The cause of this is that the second block has a p which goes below the baseline, and hence adding the \vphatom{p} to the first block does the trick.
• The reaason why the blocks are of different heights is also for the same reason: The last line on the left has a g and the one on the right has no content with descenders. This also can be fixed by adding a \strut to both of the last lines, or a \vphantom{g} to the last line on the left block.

Code: \strut

Answer 2

The word Razones has zero depth, the world Expectativa has a positive one. You can correct their behaviour, adding \strut, as it is shown.

\usepackage{mathpazo}
\linespread{1.05}

\usecolortheme{rose}
 \setbeamercolor{titlelike}{bg=structure,fg=white}

\begin{document}
\section{Lorem Ipsum}

\begin{frame}
\begin{minipage}{0.45\textwidth}
%    \begin{block}{\hfill Razones}
  \begin{block}{\hfill\strut Razones}

    \begin{itemize}
    \item Reducción del torque resistente. 
    \item Daños en la fuente original
    \end{itemize}
    \end{block}

\end{minipage}
\hfil
\begin{minipage}{0.45\textwidth}
    \begin{exampleblock}{\hfill Expectativa}
     \begin{itemize}
    \item Reducción de canales de alimentación.
    \item Tensión de alimentación estable.
