Cannot figure out flickering on iphone

I have a pretty complex interaction in the first scrolling part of my site. I just had to troubleshoot some issues with the flexbox on Safari and once I figured that out… the words “We scoured the galaxy to find the most advanced construction submittal software…” “and brought it back to you” started flickering on iphone.

I have a very tight deadline and i’m out of tricks up my sleeve, can anyone out there help me?
