Recently, due to the activity of the page, the page used the background long graph, in the page scrolling, always feel the page stuck, not smooth. Guess is out of the page rendering problem.
The browser environment where the page appears to be stuck is as follows:
The latest version of Chrome for Mac and the latest version of Edge
The long image that appears in Caton is in JPG format and is 7784px long
The solution
Changed the format of the long image from JPG to PNG. Now the scrolling page no longer has the stutoning effect.
