Google Cuts Chrome Android Scroll Jank 48% With 3-Year Architecture Overhaul

Summary
Chrome for Android reduced scroll jank by 48% from 2023 to 2026, easing the page stutters and jumps Google called a major drag on mobile web use.
A missed frame can leave a stale scroll position on screen for about 16.7 milliseconds at 60Hz, and Chrome’s separate browser, renderer and GPU processes make those delays harder to avoid than in typical Android apps.
Google said the gains came from input prediction, moving browser-control updates into the Viz GPU pipeline, and raising priority for Android threads that deliver hardware input to Chrome.
The work reflects a broader push to make Chrome’s input-to-frame timing more consistent, so every scroll update reaches the display on time despite irregular hardware input and a multi-process rendering path.
