Chrome's scroll stutter reduced by 48% on Android
Google rebuilt Chrome through 3 years of engineering work behind the scenes.
1The scroll jank problem
What Google calls 'scroll jank' occurs when Chrome fails to update the screen fast enough during scrolling. Even millisecond delays are noticeable to the human eye, disrupting the feeling of smoothness.
2Three years of optimization
Google engineers worked for nearly 3 years to improve Chrome's Android performance. They implemented multiple architectural changes including redesigning the render pipeline, optimizing touch input, and increasing GPU utilization.
3Multi-process challenge
Chrome's security-driven process separation makes its render pipeline far more complex than typical Android apps. This previously allowed numerous micro-delays to accumulate for each frame displayed.
4Performance instrumentation
Google spent months on detailed measurements to pinpoint the exact source of issues. Every step of the render pipeline was analyzed through instrumentation to identify bottlenecks.
5Android integration
The solution extended beyond Chrome. Google optimized Android OS's input threads to deliver touch events to Chrome more consistently, improving frame delivery reliability.
6Enhanced user experience
These efforts reduced scroll stutter in Chrome on Android by 48% compared to 2023. Users can now scroll through feeds and web pages with significantly improved smoothness.
