How can I fix lagging text marquees on my product page?

I have used 2 text marquees on my product page under the 2 prices and my product page is made by pagetifly ( not pagefly) but these 2 text marquees are so much lagging and it even heats up my phone, I have usde a text marque from ecomposer which is running on my homepage and it runs smoothly without any issue, anyway thanks to pagetifly having to add custom coding I NEED A TO BORROW SOMEONES CODING KNOWLEDGE. I need a good unlagging and not heating up text marquee.

Using text marquee, no matter how poorly coded, shouldn’t be heating up your phone. I would take a look at your phone and make sure there isn’t something actually wrong with it first. What’s the URL to the page you’re using it on?
