Wow! I've been having this exact same problem in the last 6 months. I've had three batches of IPA go bad to diacetyl. All three batches were HEAVILY dry hopped beers. It's never happened in any of my other beers. It's not my fermentation. I can't believe it's not a long enough diacetyl rest. I'm so perplexed. I think I'm going to keep my dry hop down to 1 oz/gal and see if that helps. I'm also going to throw out all of my yeast and start over with fresh to make sure, but I don't think that is the problem either.Yes, this taste only appears on IPAs.
A friend of mine also changed his lines to *I don't know what better tap lines* and he noticed a change in the taste of his brews for the first glass.
I never bottled carb an IPA, but I hope for you that this "too much CO2 volume" is the culprit!
