I’m also seeing this on 314. Even after clearing the app cache. Scrolling the feeds is fairly smooth in card view but you’ll see it in list view. The feed will stop scrolling at certain points and there’s a performance chug as images and/or videos are loaded(preloaded?). Toggling things like image preloading and webp conversion had no effect.
Still seeing the issue after clearing cache. It seems to get worse the more I’ve scrolled through. Primarily, when a new page of posts is being loaded and opening/closing comments (swiping to close becomes unusable)
Update with 318: The feed scroll lag is much better, BUT having scrolled for a while other parts of the app are very laggy/freezing like comments sections and settings.
