Scoll is "hard" on safari only. Why?

Hi there !

My client is experiencing a scroll bug in the homepage www.ok-ev.com (password 3360) on safari only, saying the scroll is hard and has a “resistance”.

Could you tell what it is ?

I think it could be this fixed sidebar

If it s the case, how could I optimise it ?

it’s very important i solve this bug !

Thank you in advance

Stefano
