Why the picture twitches when scrolling?

When scrolling down and then up again, Katinka slider (the top most) twitches. I can not understand why which property it affects.

Because of this: https://c2n.me/3RwX3LJ
You have a sticky menu on top when scrolling is shifted slightly downwards, immediately goes racing background, 65 pixel.

Can be corrected like this: https://c2n.me/3RwX9BD , https://c2n.me/3RwXaKc
Adaptation to small screens is not checked. It will need to check yourself.
Thank you! - Kavon.Herzog27 commented on June 8th 19 at 17:15
