Very laggy scrolling in moderately large comment threads (lemmy.ca)

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

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.
