Recomposition spikes during scrolling and animations often stem from unstable parameter changes, deferred state reads, or cross-phase back-writing. Diagnosing these issues requires reproducing the transition to measure recomposition counts and isolate the specific source driving the performance drop.

To diagnose Jetpack Compose recomposition performance issues, identify a specific scenario like a focus change or scroll, reproduce the transition, measure recomposition counts, and analyze whether parameter stability, state reads, or cross-phase back-writing drives the excessive recompositions.

Cross-phase back-writing in Jetpack Compose occurs when later phases like drawing write back to earlier phases like composition, triggering unnecessary recompositions. Identifying this pattern helps isolate performance bottlenecks during focus transitions, scrolling, and animations.

Reproducing and measuring Compose recomposition counts for focus transitions involves identifying the scenario, triggering the transition, and observing recomposition behavior. This structured review isolates whether parameter instability or deferred reads drive the recomposition overhead.

Fixing unstable parameters causing Jetpack Compose recomposition involves diagnosing the root cause and routing to targeted remediation. This skill guides you to specialized diagnostics for parameter stability and deferred state reads to implement the corrective steps.
