I am seeing the same issue as OP, on the same environment. It seems this regression was caused by a change in PR #13670. In particular the change to the sneakPeek callback in the menuable mixin. As a very quick test I just added the following line:

_this.$refs.content && (dimensions.content = _this.measure(_this.$refs.content))

to the top of the sneakPeek callback which then causes the Menu to display as expected in the app bar. Hope this helps narrow down what the issue is.

offsetParent returns null in the following situations: [...] The element has the position property set to fixed

Thanks. From what you told me on the previous issue I suppose this will be released next tuesday. I think it is quite a big regression, maybe an early relase is warranted ?

I'm doing another release today to fix the new sass issues anyway.
