Animation jerks when returning to the feed

Hello.

Apologies in advance for my english.

In general, the problem is this… If you scroll the feed from the very beginning, then everything works perfectly, absolutely smooth scrolling. BUT if you scroll through a few pages, enter one of the posts, and then return to the feed and restore the scroll position, terrible glitches begin, the feed jumps up and down almost every scroll.

I restore the position using “scrollInto”:

scrollTo(id: number) { this.virtualScroller.scrollInto( this.items.find((e) => e.id === id), undefined, -50, 0 ); }

Demo is unrealistic, the project is huge and completely decomposed. Therefore, I am attaching a video for clarity.

Help me please.

Hi @Uchit-Patel, I’ll see if I can find the fix I did a year ago and come back to you shortly (tonight or tomorrow)

Hey @rintoj , There should be an option to toggle this behavior for those who are not lazy loading the entire list. for those who are not appending or prepending items the solution I gave will solve the scrolling issue. what do you think? should i raise an PR for this?
