Avoid or reduce the white flash during scroll

[dev-kml]

If the contents in the cells are complex, the white flash during scroll (with CPU throttling / lower resource machine) is more noticeable.

Are there any recommendations on how to either avoid or reduce the white flash time?

Things I have tried:

1. Increasing the number of overscan. That kinda helps a bit, but not greatly.
2. I checked the doc and couldn't find the measureElementCache API details.
   • measureElementCache.get(getItemKey(index)) would return Element.
   • Would this even be a valid approach though? Feels like this is not going to solve the problem since the core problem is around how much resource the browser needs to take for rendering the un-rendered rows in the DOM.
