# Any idea why the $\tt hat$ “$\hat{}$” is a bit off?

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.

EDIT2: And that's the same comment rendered on my (fat32) computer:

• hmmm this is a hat $\hat{a}$ ? And I see it ok... – Fat32 Jun 12 '17 at 1:53
• Thanks @Fat32 , I don't know what's wrong on my computer but I still see the hat shifted a bit to the right. Let me upload a screenshot. – Gilles Jun 12 '17 at 18:24
• @Fat32 , I have no clue what's going on. At first I thought I wasn't the only one, so far it doesn't seem to be the case. – Gilles Jun 12 '17 at 18:40
• @Fat32 , please see my answer, now I know I am not alone. – Gilles Jun 16 '17 at 11:14

I'm not sure? It looks OK to me: $\hat a$ ?

• Thanks Peter ! From here your line's still off, got the $a$ with the hat top- right, but the image looks good. I have attached a screenshot in the edited answer. I don't know what's wrong. – Gilles Jun 1 '17 at 11:20

So I found that this has to do with the recent Safari update to version 10.1. My issue and screenshots are from Safari 10.1.1.

This is also reported on Physics meta SE, on mathoverflow meta, and explained in issue #1709 on the MathJax tracker.

UPDATE:

As of today (September 25th, 2017) with Safari 11.0, this issue has been fixed. All exponent symbols fall right in place. Cheers !

• That's interesting ! – Fat32 Jun 16 '17 at 18:52
• Could be a MathJax update, now also cases behaves more like it does in LaTeX, formatting the second column as text. – Olli Niemitalo Sep 29 '17 at 9:13
