Been there, it's no fun. I spent last year making an HTML5 game. On the day we delivered the final beta, a silent Chrome update caused an error and all of our sprites started losing their z-index and thus flickering like mad. But only in Chrome, in the newly released version. I had to tell the publisher to use Safari or Firefox while we figured it out... Which was not what they wanted to hear. That said, I enjoy developing for the platform and think the huge benefit in audience size for social games makes life on the bleeding edge worth the pain. These are the early days. It'll settle down.
