| Scroll Event Handling | Event-driven | Time-based |
| Scroll Animation | Step-based | Smooth, continuous |
| Frame Rate | Variable | Consistent, 60 FPS |
| Overscroll Behavior | Elastic, bouncy | Dampened, controlled |
| Scroll Momentum | Linear, predictable | Natural, physics-based |

Visualizing Chrome’s Scrolling Process

Imagine a web page with a long list of items. When a user scrolls down, the following steps occur:

1. Scroll Event: The browser receives a scroll event from the operating system.
2. Viewport Update: Chrome calculates the new viewport position based on the scroll amount.
3. Display List Update: The browser updates the display list, which contains the elements to be rendered.
4. Redraw: The affected portions of the web page are redrawn on the screen.

During this process, several bottlenecks can arise. For example, the display list update can be computationally expensive, especially for complex web pages. Additionally, redrawing large portions of the screen can introduce lag and affect the scrolling experience.
