While in local multiplayer (e.g. splitscreen), the second player who joins the world has their cursor/crosshairs completely disappear when the first player (whose world we are playing on) opens a chest or a crafting table, etc. This happened up until the Chasing the Skies update but I cannot confirm that this currently still happens due to a different bug that prevents splitscreen play between two different accounts. Since I didn’t see it on the update list I suspect it’s still a problem.
