Bug 243164 – Scrolling through large tables leads to checkerboarding

• Component: Scrolling
• Status: RESOLVED DUPLICATE

This ZIP contains a sample HTML page which statically renders a large table with <table> and <div> elements

While scrolling through a virtualized tables, we notice a flash of white where the contents of the table disappear when we scroll fast using the scroll bar.
To check this issue, we try scrolling through a statically rendered table of large size of rows and columns,

We notice content disappearing while we are scrolling fast using the scroll bar and pointing device.

To reproduce the issue :
1. Unzip the contents of the attached `testfile.zip`
2. Run `npm install` and then `npm start` to start a local server
3. Access the http://localhost:8080 and scroll the table and div once the page loads. (Due to the large size, it might take some time)

We face this same problem with a virtualized implementation of the Table where the cells are loaded on demand when they are scrolled in the view port.

This was probably improved by the fix for bug 242424.

I confirmed that the flashing is gone with that bug fixed.
