Microsoft is trying to make Chrome and Edge scroll more smoothly.

Although Chrome is the world’s most popular desktop browser, that doesn’t mean it’s the perfect browser without any problems. One of the design flaws is that on the Windows 10 platform, users experience scrolling through long pages. Microsoft has promised to fix scrolling issues in its Chrome browser, while Chrome-based Edge 86 has optimized the scrolling of large PDF files.

Microsoft is trying to make Chrome and Edge scroll more smoothly.

In a Chromium-based browser, users are allowed to scroll through touch, rollers, and precision touchpads. When scrolling through both the mouse and the trackpad, scrolling may be prevented if the page calls the initial value of scrolling.

By default, Chromium detects the presence of an entire frame, but does not track which part of the page has an event listener, so this behavior affects the main thread’s high-usage page or devices that use a low-power processor.

This can cause delay problems when scrolling with rollers on low-end devices. Also on high-end devices, this problem occurs when users access a large number of pages.

Microsoft is developing a feature called Wheel Event Handler Regions that correctly calculates the processing area for scrolling events on Chrome, Edge, and other Chrome-based browsers. The idea is similar to how Google Chrome currently tracks the area of the touch processor (input) and is designed to handle wheel scrolling more quickly. When this happens, Chromium does not have to wait for the main thread to start scrolling.
