Jetpack Compose Lazy layouts scroll jank and lose item state when stable keys are missing, causing unnecessary recomposition and destroyed state during list insertions, removals, or reorders.

Use contentType in Jetpack Compose LazyVerticalGrid to differentiate heterogeneous feed items like cards, headers, and ads, ensuring the layout pools and reuses the correct item composition types efficiently.

Animate item insertions and removals in Jetpack Compose LazyRow by applying Modifier.animateItem() and providing a stable key to each list item, maintaining visual continuity during data mutations.

Hoist heavy allocations outside the item lambda in Jetpack Compose lazy layouts to prevent object recreation during scrolling, validating item composable stability to minimize recomposition overhead.

Yes, this approach works for LazyHorizontalGrid and LazyColumn by applying stable IDs as keys and specifying contentType for heterogeneous lists, effectively solving scroll jank and item-state issues.

Audit Jetpack Compose lazy layouts by validating item composable stability, checking for stable keys and contentType usage, and hoisting heavy allocations outside item lambdas using layout tooling to observe recomposition behavior.
