Swiper premium - How to prevent Swiper-gl blocking the main threads

[anhdd-kuro]

I'm currently using swiper-gl for a slider positioned at the top of the page. However, I've encountered a problem. According to Google PageSpeed Insight, the main thread is being blocked by Other

Upon researching what exactly the Other is, I've come to a conclusion. The problem gone and the point up to 97%, when I remove the GL effect.

What should I do to prevent this to happen.
I've tried setTimeout, but it hasn't help too much. Additionally, since the slider is at the top of the page, using an observer to defer it doesn't seem to be providing a substantial improvement either.

 new Swiper(".swiper-top", {
      modules: [Pagination, Autoplay, SwiperGL],
      effect: "gl",
      speed: 1000,
      autoplay: {
        delay: 3000,
      },
      lazyPreloadPrevNext: 1,
      loop: true,
      pagination: {
        el: ".swiper-pagination",
        clickable: true,
      },
      gl: {
        shader: ["shutters", "slices", "polygons-wind", "wind"],
      },
    });
