I show a list of images in ListView or CollectionView. When I scroll up and down several times, I see that on Android, sometimes cells that have been shown before are now empty because their image is recycled, disposed, or hidden. I don't know what is happening, but I don't like the user experience. It takes about a second for the images to appear again. I tried using both FFImageLoading and good, old Image. Same issue. When I use Instagram, I don't see this problem as their scrolling is very smooth and previously-shown images never disappear out of their cells.
The images I display can be anywhere from 100Kb to 500Kb. Is there a setting that needs to be changed to fix this behavior? iOS seems fine.
