I am noticing that the hat accent in $\textrm{"\hat"}$ is a bit off for the past days, going top-right as an exponent. And that's for both inline and display mode. Even the entry on the famous MathJax tutorial got the "hats" off. And the $\textrm{"\vec"}$ as I see.
Maybe more accents to discover. I have seen this on other SE sites as well. Any ideas?
EDIT:
From @Peter K.'s answer down, it looks like it's only from my computer as shown on the image below:
From @Fat32 's comment (see attached image below), I am still seeing the same thing. I don't know what's wrong.
