Interactions, Images and Transitions Not Firing - Causing Flashing

I have been working on the website for my agency site, but the page load transitions, images and further smaller interactions are skipping causing a pretty jarring effect.

Would anyone know why thats started happening?

Hi guys,

Does anyone have any thoughts on this? The site runs, loads and scrolls perfectly on Safari but fails miserably on Chrome - anyone know why this could be happening? I can’t seem to locate the browser issue.

I would be happy to remunerate anyone for their expertise and advice.

Cheers guys!
