Codepen protfolio (small) issue

Hello Forum users.

As I am building my portfolio page i see a minor issue. As i scroll down the page to examine the About me section I see the first image repeat itself for a short moment before swapping to the image I have coded in. what causes this & how do you fix it? Thanks in advance for any help.

That’s a super interesting bug! I can’t replicate it for the life of me. Which browser are you using?

I don’t see a repeat - in Firefox – but I do see the tail end of the image above the about me section. Might be a spacing issue?

I use FIrefox as well. More specifically it happens when I add anything then run the page. it refreshes, I scroll down and for about .5sec the image above tiles itself before changing to the right image. i’m curious as to why/how it does it.
