Scrolling is suddenly wobbly in Chrome

Hello here I am agin, After not using my site for a while I went back to check and noticed the scrolling is totally wobbly in Chrome browser. I changed absolutely nothing on my site. Wordpress suggested to try deactivating the catch-infinite-scroll plugin to test but that changed nothing so i reactivated it. My site is www.manonwethly.com Can you please test my site in chrome and tell me what to do? Thank you! Have a good day! Manon
