If you want to wash new cloths with your old ones (especially with white clothes) you can use a color catcher. I usually use them when I’ve got new clothes and wash them for the first time.

I had the same problem not in jerboa but on desktop and I think it came from new posts loading at the top. Anyone else has this problem?

Similar here. Sometimes when scrolling down it just jumps up some posts. Using desktop.
