I'm using the SplitText plugin and have run into so many issues. Here is the code I'm using:


// split and animate the text
const split = new SplitText(this.refs.message, { type: "chars, lines" });
//targets, duration, vars, stagger, onCompleteAll, onCompleteAllParams, onCompleteAllScope
TweenMax.staggerFrom(split.chars, 0.2, {
  autoAlpha: 0,
  scale: 3,
  delay: this.props.delay || .3,
  onComplete: () => { } },



1. Performance is terrible, especially when anything else is happening on the page.


2. It frequently stops, then janks ahead several words in a very jarring way. 


3. It sometimes orphans single letters onto the next line


4. It causes horizontal scrollbars when they're not needed



Anything I can do to solve these issues?

Sorry to hear about the trouble. It's very difficult to troubleshoot blind, but it sounds like maybe you're just animating way too many things for the browser to keep up. Typically in cases like this, GSAP is only consuming a tiny portion of the CPU compared to the browser's rendering engine. It'd be helpful to see a reduced test case. Maybe a codepen or jsfiddle?


Also, have you tried splitting by words too so that the orphans don't happen? That'd likely solve that problem (because the word <div> would keep stuff together).  


If you're trying to animate a ton of letters, you might want to look into a canvas-based solution like Pixi.js for the rendering layer. Use GSAP, of course, for the animation, but I'd be willing to bet that the problem here has nothing to do with GSAP and everything to do with pushing the browser's rendering engine too hard with all those DOM elements.
