Improvements in Microsoft Edge Performance Scrolling

Edge Chromium is gaining more and more ground as a browser and one of the reasons for this is Microsoft’s efforts to improve scrolling in Edge. As an action, scrolling is one of the most common user interactions, and poor scrolling can ruin any experience, regardless of browser quality.

What makes scrolling good? Microsoft suggests in its latest Windows blog that a user needs fast and responsive scrolling regardless of input method. In this post, we summarize how Microsoft’s experience has helped them understand how to improve the scrolling personality in Edge, and some upcoming changes will improve performance and functionality.

Based on the thousands of responses received from those using the Canarian version of Edge, the feedback provides the following details:

  • 41% on personality
  • 39% on functional issues
  • 13% for specific performance issues
  • 5% for PDF scrolling
  • 2% General feedback

With this in mind, the Microsoft Edge team has decided to focus its efforts on personality and performance. Once Microsoft achieves this, the scrolling experience will be as good as the native Windows 10 experience.

Enhanced Pulse and Touch Animation Curves

One of the improvements we are making to Chrome is a new animation curve for scrolling. This curve gives the mouse wheel, keyboard, scroll bar or touch the “smooth” personality found in the previous version of Microsoft Edge.

Overall, the animation is more tactile, slightly longer, and with less abrupt speed changes. We suggest you try it today in the new Microsoft Edge on a Windows 10 device by scrolling the mouse with the scroll wheel, keyboard or scroll bar, or by touching an adventure.

We now recommend using this tool for your error. Additionally, this tool fixes common computer errors, protects you against file loss, malware, hardware failures and optimizes your PC for maximum performance. You can fix your PC problems quickly and prevent others from happening with this software:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.


Scrolling based on percentages

Chrome browsers use a fixed scroll delta value (100 px per mouse wheel check mark, 40 px per click on the scroll bar or by pressing the keyboard arrow). We are modifying this behavior to match earlier versions of Microsoft Edge that use the height of the scrollbar to calculate scroll deltas. Percentage-based scrolling is an excellent functional addition that makes navigating small scrollbars much easier.

Bounce effects on root scrolling.

Scroll bounce is a signal to the user that they have reached the end of a page while scrolling,” explains Microsoft. (Some call it “rubber banding.”) In its user studies, Microsoft has found that more than 70 percent of users prefer the scroll bounce effect, so it is now enabled for both touchpad entries in Edge when scrolling in either direction.

In addition, Microsoft has also changed some behaviors between the old and new Edge, as some behaviors were not very popular. A feature called Scroll-Chaining – an effect that scrolls the parent scroll as soon as the underscroll reaches its limits – was considered a bug by many users and was therefore removed. Edge now uses a feature called “scroll latching”, where all scrolling manipulations are directed to the same scroller until a certain amount of time elapses without scrolling. The company has also removed Quick Flick, which created large scrolling deltas when a user made a short but quick movement on the screen.

What’s next?

Microsoft’s goal is to bring together the best of Microsoft Edge and Chrome to create the best browsing experience available on the market. Although I don’t often think about scrolling through this level of detail, I appreciate that Microsoft is listening to its users and is constantly trying to improve its browser.
