please keep in mind that there are dozens (possibly hundreds) of
people who have not hit this behaviour. this means that it could be
rather useful to everyone to debug what is actually going on. i
understand if you don't have the time, but i can't reproduce this and
as far as i'm aware neither can any of the other core alpha testers.
finally, its note entirely impossible that this is caused by jack2 and
its interactions with ardour3. i do not test jack2 at all, and i think
most alpha testers (though definitely not all) are also using jack1.
