Tracer Losing Target Focus Bug

When i Play Tracer and i target Hanzo, ik lose target focus on Hanzo.
i need to refocus Hanzo to get target fix. it also happens when there are minions around. please look into it. This is not only against hanzo. but i mentioned Hanzo because it happens much more often then against other characters. Thx

Could it possibly be happening as a result of losing sight? I have been playing Tracer for the last 30 matches and didn’t experience any trouble.
