what transport issue? oh i see... :)

qtractor has in fact a known trouble with jack transport sync when slaving
to period/buffer sizes greater than 2048 frames. it skids. maybe that's
exactly what you're experiencing when running jackd -p4096.

i'll recommend for you to turn jack transport mode to "none" or "master"
only, never "slave" nor "full" on those situations (in
view/options.../audio/jack Transport).

another recommendation would be to grab the latest from svn trunk where
the said trouble has been already mitigated :)

cheers
