When scrolling the feed with compact mode on, thumbnails are loaded while posts are shown.
Some sort of lazy loading would be awesome here. So thumbnails would get preloaded before you actually scroll down, thus you’d never see the actual loading happen.
Would look and feel much smoother.
They don’t need to cancel each other out.
Lazy loading usually means to load the image at a lesser quality to have something to show the user very fast, so yes technically this can be called opposite of pre loading if used solo.
Pre loading in this instance usually means loading before the user sees the image.
These 2 things can be used together, an example could be to lazy load images at a low quality that are further down the feed before you scroll to them, and load the full image as you get closer to it/have it show on the screen.
But I’m sure the devs knows about thease tricks already
