Yesterday, Microsoft released an update for Chromium Edge users of canary and Dev channels. This brings some changes and improvements, as well as a new feature designed to improve the browser scrolling experience. To make it easier to experience the improvements from Compositor Threaded Scrollbar, the company even created a sample website.
For friends who want to taste something fresh, refer to the following steps:
(1) Enable Edge Canary or Dev, then disable the Compositor Threaded Scrollbar Scrolling tag;
(2) Reopen the browser and go to the Microsoft Sample Website (GitHub Portal);
(3) Click ‘Start Animation’ and ‘Trigger Main Thread’ in the upper left corner (Induce main thread jank).
In this case, you will notice that the vertical downward scrolling operation has a significant delay.
You can then go back to re-enabling the “Compositor ThreadedThread Scrolling” tag to see the difference between the two experiences.
In addition, Microsoft has released complete design documentation for this feature for developers who need it to refer to and check.
Interestingly, Google Chrome Stable currently does n’go of this new feature pioneered by Chromium Edge.
Finally, Microsoft submitted a bug to the Google Chromium team, and the fixes were pushed simultaneously to other third-party browsers based on the kernel.
