Does everyone else have a speed enchant of some sort but she doens't?

Try moving with the problem alt's window up front, see if it still breaks;(unbind all but main's movement keys temporarily so only the main moves, and allow keyclone to pass them temporarily so you can keep the alt up front); could be that one wndow's lagging for some reason or maybe it just has an extra keybind left bound you didn't realize(Like my third alt had turn with q and e left on but my 2nd didn't)
