Our users have been experiencing an issue while scrolling through a topic. At a certain point, when more posts need to load, a loading spinner appears at the bottom. However, as soon as the new posts load, the page suddenly jumps to the very last post in the topic. This happens quite frequently, and I’ve noticed it’s worse if the user scrolls faster.
The issue occurs across multiple browsers, including Brave, Firefox, and Chrome on Android, as well as Safari and Chrome on iOS.
After upgrading the Discourse core on December 24, 2024 (4ccbf5c5ad), it seems like the problem has become even more common.
