Really Slow CSS Animations (worse on Chrome browsers)

Question

I am having issues with lag when using a combination of two CSS animations. The first one animates text shadow on a text, and the second animation is animating two SVG's in the background. On Firefox it doesn't lag very much, but on Chrome it's really bad. Here is a video of it.

Here is a snippet:

/*NEON TEXT CODE*/

#flicker {
  animation: flicker-text 1.5s infinite alternate;
  font-size: 36px;
  color: white;
}

@keyframes flicker-text {
  0%,
  18%,
  22%,
  25%,
  53%,
  57%,
  100% {
    text-shadow: 0 0 4px #fff, 0 0 11px #fff, 0 0 19px #fff, 0 0 40px #B0D9DD, 0 0 80px #B0D9DD, 0 0 90px #B0D9DD, 0 0 100px #B0D9DD, 0 0 150px #B0D9DD;
  }
  20%,
  24%,
  55% {
    text-shadow: none;
  }
}


/*OCEAN AND WAVE CODE*/

#ocean-container-vs-code {
  position: fixed;
  top: 0;
  left: 0;
  z-index: -9999;
  height: 100%;
  width: 100%;
}

.ocean {
  height: 5%;
  width: 100%;
  position: absolute;
  bottom: 0;
  left: 0;
  background: #015871;
}

.wave {
  background: url(//dd7tel2830j4w.cloudfront.net/f1659025056348x434203136138475760/wave.svg) repeat-x;
  position: absolute;
  top: -198px;
  width: 6400px;
  height: 198px;
  -webkit-animation: wave 7s cubic-bezier(0.36, 0.45, 0.63, 0.53) infinite;
  animation: wave 7s cubic-bezier(0.36, 0.45, 0.63, 0.53) infinite;
  transform: translate3d(0, 0, 0);
}

.wave:nth-of-type(2) {
  top: -175px;
  -webkit-animation: wave 7s cubic-bezier(0.36, 0.45, 0.63, 0.53) -0.125s infinite, swell 7s ease -1.25s infinite;
  animation: wave 7s cubic-bezier(0.36, 0.45, 0.63, 0.53) -0.125s infinite, swell 7s ease -1.25s infinite;
  opacity: 1;
}

@-webkit-keyframes wave {
  0% {
    margin-left: 0;
  }
  100% {
    margin-left: -1600px;
  }
}

@keyframes wave {
  0% {
    margin-left: 0;
  }
  100% {
    margin-left: -1600px;
  }
}

@-webkit-keyframes swell {
  0%,
  100% {
    transform: translate3d(0, -25px, 0);
  }
  50% {
    transform: translate3d(0, 5px, 0);
  }
}

@keyframes swell {
  0%,
  100% {
    transform: translate3d(0, -25px, 0);
  }
  50% {
    transform: translate3d(0, 5px, 0);
  }
}


  
    
    
  

This is some test text

Does anyone have any insight on why combining these two animations causes severe lag? What am I doing wrong here?

Thanks so much!

EDIT: Pay attention to when the text flickers. On the moment the text flickers, the waves lag.
