kdenlive-19.12.0 and 19.12.1 too slow to be usable

FYI, I fecthed and installed:

https://pkg.freebsd.org/FreeBSD:11:amd64/release_3/All/kdenlive-18.12.3.txz

which works much better.  I still get noise on tty - presumably from
some of the libraries that kdenlive uses (there are all still from
quarterly collection), but kdenlive works better, playhead tracks video
ok and audio plays in sync.
