High-performance scroll FFImageLoading Win3

[artillisprado]

I'm building a desktop application using .NET MAUI (Windows) that displays a large number of images (between 200 and 1000) in a CollectionView. However, I'm facing serious performance issues when scrolling:

When scrolling quickly, the app crashes without clear errors or logs
I've tried performance optimizations, but the CollectionView in .NET MAUI still lacks full high-performance scrolling support on desktop

I found code using ScrollStateChanged (as in WinUI 3), but it's not directly supported in .NET MAUI.

_myListView.ScrollStateChanged += (object sender, ScrollStateChangedEventArgs scrollArgs) => {
switch (scrollArgs.ScrollState)
{
case ScrollState.Fling:
ImageService.Instance.SetPauseWork(true); // all image loading requests will be silently canceled
break;
case ScrollState.Idle:
ImageService.Instance.SetPauseWork(false); // loading requests are allowed again

  // Here you should have your custom method that forces redrawing visible list items
  _myListView.ForcePdfThumbnailsRedraw();
  break;

}
};

I'd appreciate help with:

Whether there's a viable alternative to CollectionView for high-item-count scenarios
