Incomplete frames making it into motion video stream

Question

Ever since netcam_tolerant_check was added to motion, I have had trouble with partial frames showing up in the movies that motion creates. Prior to the release of the netcam_tolerant_check capability, motion would filter out the partial frames instead of including them.

I have:

netcam_tolerant_check off

set in my motion.conf.

Please see the example video attached to this support question below.

Why do I see partial frames?
