New, Low-ranked posts continuously popping up to top of homepage

I am new to Lemmy and am struggling with a usability issue that is making it virtually unusable. Every few seconds (I am assuming every time a new post is made) a new post pops at the top of the feed, no matter what my sorting method is. This causes any post I had open to close and for all posts to bump down which means I can’t easily read any headlines. When I browse all federated instances this is even worse as there are many more new posts.

Is this expected behavior? How can I prevent it? I tried different sorting modes and had no luck. Any advice or pointers would be much appreciated.

Also, I wasn’t sure which community to post this question to so please fee free to move it if needed.
