[kdenlive] Title clip obscuring *some* video tracks

Sounds like your title layer is trying to composite against nothing when 
the the video goes to track 3 due to your transition pointing at the 
next track down which doesn't exist.

You can fix it by splitting up your transitions so that you have 
multiple of them on your title track, and then manually set the track 
that it composites with in the transitions setting.  See in the attached 
screen shot where in the transition settings at the top it says "Type 
Affine with track Video 3"

The other transitions you can leave set to Auto or Video 2 and they will 
continue to work as usual.

This is just what I've noticed over time.  I haven't quite wrapped my 
head around the order that kdenlive does compositing when you have 
multiple layers to deal with so I would love a long explanation of 
compositing order.
