UI elements that take scroll input (ie when scrolling in a menu/creative menu/hotbar) don't seem to take into account the scroll wheel/touchpad scroll change amount. This means that even a very small change value (such as residual velocity from a touchpad "flick", or any input from a high dpi mouse wheel) will trigger many scroll actions, and since every scroll action seems to be treated the same, the menus/hotbar scroll farther than needed (sometimes by a lot). This problem seems to have existed in the game for many releases (as long as I can remember). The scrollable chat history seems to one of the few things that take into account the change amount.
