RE: mid-measure key change

[Mark Stephen Mrotek]

Mr. Kastrup,

Thank you for your expenditure of time and effort on this matter. Your reply
is appreciated.
Alex Loomis has offered a suggestion - make two 2/2 measures. I have yet to
try it in context.

I don't see an obvious solution (but then I don't understand the bug) but I
boiled down the example somewhat more, killing most of its musicality but
making the problem more apparent.  I was suspecting the tuplets to be
involved, but no.  In the following, outcommenting the line with the Staff
\change cures the problem.

If no other developer has a good lead, this should be picked up by the bug
squad and turned into a report.

As for a workaround while this bug is not fixed: does anybody have an idea?
I've tried a few things with Y-extent without success, but that's probably
because I don't understand the bug in the first place.
