Adobe Target - Personalization of a bootstrap component

Hi all, 

we are trying to configure an A/B test changing the pictures order of a carousel component handled by boostrap. 

Are there best practices to manage the flicker issue apart of the pre-hiding snippet?

Because we are trying to implement it on our site but doesn't help with the rendering of the images. 

The component we are modifying with the VEC is a bootstrap carousel, so are there any consideration to do when working with a dynamic component as this is? 

Thanks 🙂
