How do I stop my images and icons from flickering in the chrome browser?

[Yasmine901]

I've optimised my site the best I can but I'm still having issues with excessive DOM size. My store is less than 7 days old and I don't have much content on there so I'm trying to figure out what could be causing this. I reached out to a shopify optimiser on fiverr and she said my site is good for ecommerce standards but this is really bothering me.   

I'm hoping someone can help me fix this.
