I have a list with a single column with about 350 items using the modern experience.

 

When scrolling fast through the list, the page keeps rendering new items and removing the ones that are no longer in view

This creates a very slow performance because it takes a few seconds each time to render new items. Using the browser search is also impossible because items that are not visible on the display do not show up.

This issue doesn't exist in the classic experience. I can have 1000 items and set the view to load them all. 


Is there a way to cache or load all items in the modern experience? It feels like a huge downgrade from the classic experience in terms of performance.
