GSAP animation jank typically happens when animating layout-affecting properties instead of transforms and opacity, which forces the browser to recalculate the layout and triggers scroll lag.

Optimize ScrollTrigger animations by using GSAP batching and quickTo to minimize layout thrashing during high-frequency updates, and apply will-change strategically to offload compositing work.

Apply will-change strategically only to elements actively animating transforms in GSAP, avoiding over-optimization across the entire page to prevent excessive memory consumption and maintain smooth rendering.

Yes, you can use GSAP quickTo to prevent layout thrashing on scroll by replacing standard tween updates with highly optimized function instances designed for high-frequency property changes.

Animating opacity and transforms in GSAP improves scroll performance by keeping rendering work on the compositor thread, effectively bypassing the main thread's layout and paint recalculation phases.

Use stagger instead of standard tweens in GSAP timelines when animating multiple elements, as it batches execution to reduce layout thrashing and optimize high-frequency scroll-triggered updates.
