Recently I have faced a problem in which the \frac{}{} tex command is not rendered properly by my chrome browser. The line between the denominator and numerator gets longer than desired. In Mozilla there is no such problem. Is there is something wrong with my browser?

I have attached the image below. The image is of this answer.

Also the problem is not only with this particular post, it is with all the text that uses
\frac{}{}.My google chrome version is $(21.0.1180.41)$ and I am using windows $7 ,64$bit system.
I would like to mention one more thing as I right-click on the math expression > Math Settings > Math Renderer > SVG.Then this problem doesn't arises.And if instead of SVG ,HTML-CSS is choosen than the problem persists.

• I'm using Chrome 20.0.1132.57 on Windows 7 64-bit, and it looks fine to me. Which operating system are you using? – Zev Chonoles Jul 13 '12 at 17:50
• @ZevChonoles My google chrome version is "google chrome (21.0.1180.41)".And I also using Windows 7 64bit. – Saurabh Jul 13 '12 at 17:52
• I will look into it next week (am on the road so can't do it before then). Does reloading the page help? – Davide Cervone Jul 13 '12 at 18:20
• @DavideCervone Thanks for your time sir.Well reloading doesn't help.Also before this problem occurred I had installed LyX.Can it remotely be the cause of the problem? I don't know much about Latex and mathjax etc so I may be talking nonsense here. – Saurabh Jul 13 '12 at 18:30
• The thread you link to looks fine for me, but I see something similar in this answer (Mac OS X 10.6.8, on both, Safari 5.1.7 (6534.57.2) and on Firefox 13.0.1), but I can't tell if this is related. – t.b. Jul 14 '12 at 8:57
• Did this do the same naughty thing with ${\over }$? – ncmathsadist Jul 14 '12 at 23:18
• @ncmathsadist I didn't understand you question !! – Saurabh Jul 15 '12 at 7:19
• I am not able to reproduce the problem, but I only have version 20.0.1132.57 which my Chrome says is up to date. Are you using a beta version? Chrome is buggy enough in its release versions, so I wouldn't be surprised if this were a new bug. In any case, we're not prepared to make changes to MathJax for beta versions of browsers that may not be present when the version is released. – Davide Cervone Jul 16 '12 at 16:34
• @t.b., what you are seeing is a different issue (having to do with automatic line-breaking within the numerator of the fraction). I'll look into that, too, but it is a separate problem. – Davide Cervone Jul 16 '12 at 16:34
• @ncmathsadist, yes, {...\over...} works internally in MathJax the same as \frac{}{}, so both should produce the same results. – Davide Cervone Jul 16 '12 at 16:42
• @SaurabhHota, does this happen for you with all fractions, or just the ones on the page you cite? – Davide Cervone Jul 16 '12 at 16:42
• @SaurabhHota, did you zoom in on the page when you had this problem? I have another report similar to yours, but it is dependent on zooming in or out. – Davide Cervone Jul 30 '12 at 15:36
• @DavideCervone No I didn't tried zoom in back then but now my problem is solved as I have changed my google chrome version. – Saurabh Jul 30 '12 at 15:42
• Right, they released v21 a day or two ago. I will have to look into it more closely now. Thanks for the extra details. It looks like they have messed up the relative dimensions during zooming. – Davide Cervone Aug 3 '12 at 22:16
• I have opened an issue tracker on the MathJax GitHub site for this problem. – Davide Cervone Aug 3 '12 at 23:10
