Simultaneous rendering of multiple JSON vector animation frames can throttle a client CPU. By default, browsers paint updates to the layout tree, which triggers layout cycles and paint storms.
Layer Composite Optimization
Always enforce hardware acceleration on lottie canvas containers by applying CSS rules like transform: translate3d(0, 0, 0);. This forces the browser to isolate the canvas rendering into its own GPU composite layer.
Lazy Loading Playback
Do not let off-screen animations run in the background. Use the Intersection Observer API in JavaScript to pause Lottie playback once the animation container exits the active viewport. This saves vital CPU overhead.
