Spacing between block title and contents is off

[a3nm]

Hi,

I'm having a problem with the metropolis theme, which I think is a recent regression (the problem now appears on documents that were fine when I compiled them with an earlier version). I'm using the version of Metropolis shipped with Debian testing, texlive-latex-extra version 2017.20171128-1.

Here's the MWE:

\documentclass{beamer}
\usetheme{metropolis}

\begin{document}
\begin{frame}{Frame title}
  \begin{block}{This line is too close to the text below}
    This line is too close to the text above, when compared to the spacing
    between the lines in the theorem environment.
  \end{block}
\end{frame}
\end{document}

Here's how it compiles for me:

Compare to the version without \usetheme{metropolis}, where the spacing is much more reasonable:

Can you reproduce this? Any idea of how to fix this? Thanks!

FYI, one workaround is to add \vspace{0pt} at the beginning of the block contents. But still, this is a bit strange...

I have also experienced this with my latest compilations.

I can confirm the issue with LuaTeX Version 1.0.4 (TeX Live 2017/Arch Linux)

Hmm, I cannot reproduce this on a Ubuntu 17.10 VM with TeXlive 2017. I also don't find the spacing reasonable at all even without metropolis …

Same problem here using MacTex 2018. (I didn't install metropolis from this github repository.)

[emilioj]

Same problem here! (using the Metropolis theme included in Debian sid's texlive-latex-extra package)

I'm attaching a snapshot with the demo.pdf included in the documentation (right) and the one generated by me (left)

[LucaFranceschini]

Same problem here, using TeXlive and the included metropolis theme, Arch Linux.

[rougier]

Same here with TexLive 2017 and TexLive 2018 (on OSX).

Alright, I can replicate the issue on my Ubuntu 18.04 box. However, I am on vacation and have no real estimate when I can fix it. Feel free, to jump in :smile:

This appears to work for me, but it's tremendously cargo-culted:

@wence- it seems to work so I'll use it at least temporarily as a workaround. Thanks!

The drawback: (ugly) extra space when an itemize is the block's content :-/

Same problem here with the latest TeXLive 2018 on Archlinux (installed from pacman) and Windows 10 (official installer), also with the latest MacTeX 2018 on macOS 10.14.2 (installed from Homebrew), compiled by xelatex.

[dbogatov]

Same problem in June 2019.

[jacr13]

I have fix it in my case using this :

% map defaulf block to oldblock
\let\oldblock\block
\let\endoldblock\endblock

% change block by adding smallskip
\renewenvironment{block}[1]
    {\begin{oldblock}{#1}
        \smallskip
    }
    { 
    \end{oldblock}
    }

[ThreeFx]

Can confirm this is still an issue with TexLive 2019 under Arch Linux.

[FinnStutzenstein]

Still an issue under Debian within TextStudio

[gsbabil]

Same issue continues in MacTex (mactex-20200407.pkg). Thanks.

To anyone else coming across this issue, @jacr13's comment worked for me - to have it working for example and alert blocks I had to essentially copy it twice and do block -> exampleblock etc!
