I'm using the \begin{multicols*}{2} environment to typeset two-column text for a cd booklet. However, the columns aren't always properly aligned vertically. Concretely, I assume that whenever there's no extra “glue” the column isn't justified vertically. The attached image shows that the right column is somewhat shorter than the left, where the space before the subsection heading is stretched out.
I have manually done \setlength{\parskip}{0pt} at some point before if that is of relevance.
How can I make multicols space out the right column (and all other affected ones) as well?
