* [Bug] Org-beamer block display math

When marking a block to call out display math, I notice an extra line
break above the display math. I believe this occurs because the block
is given it's own section.

I expect the math to be centered vertically within the block. Is there
a workaround?

Please reference the screenshot (it's small) in lieu of me posting the
org and pdf files. They're both in the shot.

Thanks for any help.

I've noticed this as well recently [1].  However, I do not believe it is
anything org is doing as the latex code generated is quite
straightforward.  For instance, I get:

--8<---------------cut here---------------start------------->8---
\begin{column}{0.5\textwidth}
\begin{block}{Model}
\label{sec-3_1_2}


      \begin{align*}
        \Diff{T(x)}{x} & = - \frac{Q}{kA} \\
        T(0) &= 600 \\
        T(L) &= 20
      \end{align*} 
\end{block}
\end{column}
--8<---------------cut here---------------end--------------->8---

The two blank lines between the label and the beginning of the align do
not do anything.  The extra space in the resulting block in the PDF is
there whether these lines are there or not.

I've taken to inserting

    #+latex: \vspace*{-0.5cm}

just before my maths.

HTH,

Footnotes: 

[1] which only means that I have started doing a significant amount of
    beamer work in org after a break of a number of weeks so any changes
    in org et al. could have happened any time in the past couple of
    months...

I noticed this as well.

That works, fine. Thanks for the tip!
