Smoother scrolling: How we halved scroll jank in Chrome on Android

In Chrome's multi-process pipeline, delays can disrupt visual fluidity, leading to missed deadlines and stuttering scrolls. The complexity of the input-rendering pipeline makes it challenging to identify the causes of scroll jank. Comprehensive instrumentation has been implemented to analyze the pipeline from input generation to GPU buffer presentation.
