I am having the same problem with a Galaxy S III SGH-T999 stock non rooted 4.1.1 (Tmobile USA). GW doesn't auto update for Gmail, but does for SMS and missed calls. Not sure when this issue started. I'm not even sure if it ever auto updated on the S III. I'm using Nova Prime launcher, but I tried using the widget in TouchWiz and had the same problem. I've tried different widget related settings in Nova without any success (including hidden "labs" settings). Not sure if it is related, but I'm having what appears to be the same issue with APW Google Reader. The stock (ugly white) widgets work just fine. I really like this widget, so I'm hoping you can fix this.
