It seems like the character moves as if wearing skates on an ice rink. Once you click on a direction then click somewhere else it seems like characters have too much momentum and continue moving of their own accord.
It’s annoying when clicking on a vendor to sell junk and the vendor moves after you’ve already clicked them. The game engine forces your character to move to the spot where the vendor used to be at a second ago instead of where they are now.
Even more annoying is avoiding clicking on gem shrines so you can make flawless gems into perfect gems. I curse when accidentally clicking a gem shrine before I’ve stocked a flawless gem. Cramped locations like Kurast dungeons suck for this.
Some other posts say controller is better movement in D2R than keyboard+mouse . . . but I’m not fond of playing with controllers. Ah well. /mini-gripe
