Re: Problem with rendering chords + lyrics at the same time in 2.13.6-1

[Trevor Daniels]

This is a bug, but it is quite hard to nail down.

It seems that Lily tries to cram too much onto a
page, and in the attempt causes the chords line
to overlap with the staff.  Any change which
causes Lily to generate an extra page provides
enough space to render correctly again.  This
might be changing any of the \paper variables,
adding notes or lyrics, etc, making it seem non-
deterministic, but of course the behaviour is
deterministic, just complex.

Karai, does this explanation match what you observe?
