How can live modifying a Lottie object not cause image pop-ins on Safari?

In handling Lottie animations, ensuring compatibility and performance across different browsers is critical. Particularly on Safari, we often encounter flickering or stuttering issues. To modify Lottie objects in real-time without causing flickering on Safari, we can take the following steps:

1. Optimize Lottie files: Ensure your Lottie animation files are as optimized as possible. Large files or overly complex animations can cause performance issues, especially on devices or browsers with limited resources. Use Lottie editing tools like Lottie Editor to remove unnecessary layers and assets, reducing animation complexity.

2. Use CSS layering techniques: If the animation flickers on Safari, try placing the Lottie animation on a separate CSS layer by setting the container to will-change: transform. This property informs the browser that the element may change, enabling it to optimize rendering performance.

   css
   .lottie-container {
       will-change: transform;
   }

3. Load and modify animations incrementally: When the animation data is large or complex, load the animation data incrementally rather than all at once. This can be achieved by dynamically loading JSON data or segmenting the animation into parts. Similarly, when modifying Lottie objects, perform changes in batches to avoid performance issues from large updates.

4. Use the latest version of the Lottie library: Ensure you are using the latest version of the Lottie library, as new versions often include performance improvements and bug fixes. Updating to the latest version can enhance compatibility and performance.

5. Pre-test and debug: Thoroughly test the animation on Safari before deploying to production. Use developer tools to monitor performance and identify potential optimization points. If issues arise, try adjusting the timeline, speed, or complexity of the animation.

By following these steps, we can effectively reduce flickering issues when modifying Lottie animations on Safari. In one of my projects, by optimizing the Lottie animation file and using CSS layering techniques, I successfully resolved the animation flickering issue on Safari, improving user experience and animation smoothness. I hope these methods can also help your project.
