This is happening on all three trilogy sites. It is also happening at Ask Ubuntu and Home Improvement, as well as on the beta sites Crypto and Expatriates, but it is not happening at Travel. Those were the only sites I checked.
The question itself, votecell and user card are pushed over to the right about 24 pixels relative to where they used to be yesterday, and where the answers still are.
In the example below, I can see in Chrome's console that td.votecell in the answer is 61px wide, while td.votecell in the question is 109px wide.
