I can confirm this now. We have multiple conflicts with NextGen gallery.
1. The download size gets 0
2. On one of my installs, the user create gallery page stopped working.
PS: If you are using WordPress 4.7.1 or 4.7.2, there is a bug that does not allow uploading non image files. I suggest using https://wordpress.org/plugins/disable-real-mime-check/ for the timebeing until it is fixed in WordPress core.
