# Keep column height in Beamer when replacing content

I have a frame in Beamer that consists of two columns. The content of one column remains the same, the content of the other column is replaced on the second slide.

\begin{frame}
\begin{columns}
\begin{column}{.5\textwidth}
% some static content
\end{column}
\begin{column}{.5\textwidth}
\begin{onlyenv}<1>
% some tikz picture
\end{onlyenv}
\begin{onlyenv}<2>
% some other tikz picture
\end{onlyenv}
\end{column}
\end{columns}
\end{frame}

The problem with this configuration is that since the height of the second column changes, the position of the content of the first column also changes, and so the transition between the slides is not smooth - The first column "jumps" around.

How can I keep the first column static, while changing the seconds?
