Sticky shaky in safari

Hi,
I am facing a problem with sticky element when viewed in safari and everything works good in chrome. There are few sticky children elements inside a sticky container. when the page scrolls each get sticky at a particular distance from top. At this point the elements looks so shaky when website is viewed in safari. Can anybody please help me on this?
Appreciate for all the help and suggestions.

Thank you,
Febin
