Coco Rosey review for Linkpop

Linkpop is promising and I had fun setting it up which was easy by the way. However, I notice that the page flickers on Instagram if you are using an image as background instead of just color. The back image moves as you scroll which causes the make to flicker which is annoying. I thought perhaps the size of the image I was using was too big, searched online for recommended size for background image on linkpop but didn't see any. Shopify don't even have anything about background image size for linkpop on their official website.
