Please tell me I'm not the only person who has this problem

When I play league I usually hold down the right click to move, and when I do that on Syndra it makes her move a little wonky. I was just wondering if anyone else had this problem with Syndra, hopefully it can get fixed because its kinda annoying to move weird playing her. Syndra would turn like really fast then go back straight, or sometimes she'll do it twice in a row, its super annoying to deal with that. Please help. By the way it only does it on Syndra and no other champion.
