Glitchy image loading on custom horizontal scroll (Swiper)

Hi, on a project page, images keep glitching on the first load, then if you reload the page, the animation performs correctly.

Find below the link to the project page template.
You can test the glitch by accessing any given project from JACKYTWOSTEP — Projects Index

Please help!

Hi I don’t see any glitch on my end.
