Parallax region sneaking out of region

Greetings!

I'm having a repeated issue occasionally popping up where a region above a thinner region is being leaked/bleeded through underneath the thinner region below.

I'm not sure if this is a similar issue to the issues talked about here:
https://premium.wpmudev.org/forums/topic/parallax-on-mobile-delay-issues/
or not, though they do seem they may be connected.

Hope there is some awareness of this issue and possibly a solution!

Much Love,
Ciro Bey
