Can you reproduce the behaviour at a safe altitude?
If so, can you rig a pair of cameras, such as GoPros to see what the slats on each wing are doing, as per the video in an earlier post?
If the cameras don't have audio you would need a synchronising signal to align the two videos in time such as a simple camera flash illuminating the cockpit interior fired off before and after the events you're interested in.
This way you can determine whether there is any uneven movement or, more importantly, asymmetrical operation of the slats.
If you're really keen, you could film either the cockpit controls or the rudder (ailerons already being in view of a camera filming the slats) to check for unconsious/inadvertant control inputs. Mind you, I'm not sure where you would put a camera to see the rudder from a Socata cockpit!

Obviously if you can assess the slat synchronisation visually, without cameras, do that first!
