I’ve noticed this in the larger threads (several dozens or hundreds of comments), scrolling becomes extremely laggy.

Edit: the lag doesn’t seem it be caused by large threads, but by threads containing comments with embedded images

    Hmm, there were some optimizations made for long comment threads, but there’s definitely improvements that could be made. Could you open up a GitHub issue on this so that we can track it easier? It would also be good to know the device you’re using and OS version!

      Actually, I don’t think it’s large threads that causes the lag. I just opened some threads with >1k comments and they worked okay.

      I think it’s threads containing comments with embedded images. Maybe those should be lazyloaded or loaded on demand?

        I tracked down a bad performance issue related to the comments list. I’ve submitted a fix so you should hopefully see a smoothess boost once that gets added into a release.

        There is still some jank with threads that have lots of images. It can cause the comment list to teleport a bit. I think it has to do with the images loading back in but I’m not 100% sure. Needs more investigating.

    I’ve noticed this too. On a Pixel 6 pro if that helps.
