Dear list,
when I typeset multi line equations using mathalignment and grid the descenders
of the last line of equation run into the first line of text after that
equation. The problem is particularly bad with the Lucida fonts (I think the
large operators are relatively larger than for Latin Modern).
I could just increase the spacing after equation (commented out in the MWE
below), but that would introduce an imbalance between space before and space
after for all equations without descenders. Furthermore the problem does not
arise for single line equations with descenders. Without grid there is also no
problem.
How do I fix mathalignment to prevent this?
Cheers, Henri
