Despite being the most popular desktop browser in the world,
Google Chrome is plagued with multiple issues, including a
design flaw that affects how you scroll through long webpages
on Windows 10.
Microsoft has promised to fix scrolling in Chromium browsers
Edge 86 also comes with scrolling improvements for long
According to a new design
doc, Microsoft is now working to make wheel scrolling
faster in Chromium-based browsers, such as Chrome.
In Chromium browser, you can scroll via touch, wheel, and
precision touchpad. Wheel scrolling works via both mouse and
touchpads, but there’s a bug that could block scrolling when
the webpage calls for a value at the initiation of the scroll.
By default, Chromium detects the frame-wide existence, but it
does not track what portion of the page has the event listener
and thus, this behaviour affects pages with heavy main thread
usage or devices using the low-powered processors.
For example, you might experience latency issues when starting
a scroll through the wheel on low-end hardware. Likewise, this
limitation also affects heavy pages on high-end hardware.
Microsoft is working on a new feature called “Wheel Event
Handler Regions” that will compute correct wheel event handler
regions in Google Chrome, Edge and other browsers on Windows
This idea is similar to how Google browsers currently track the
regions of touch handlers (input) and it aims to handle wheel
scrolling more responsively. When it happens, Chromium wouldn’t
need to wait for the main thread before starting a scroll.
If you’re scratching your head over the above technical
explanation, don’t worry: we were too.
In layman’s terms, Microsoft wants Chrome or Edge to support
“Wheel event handler region” that will improve wheel scrolling
using mouse and touchpad on devices with underpower CPUs.
The current implementation in Chromium browsers is causing some
not-so-smooth scrolling on some websites, such as YouTube. With
this new feature, Microsoft aims to reduce latency or lag when
scrolling and allow browsers to handle your wheel scrolling
