Some integral signs on M.SE are not rendering correctly for me. I've been having this problem for at least a few months, and it persists when I refresh the page. The problem is rare but frequent enough that it's annoying.

enter image description here

As you can see, the top part of the integral sign is cut off. This is a screenshot of a section of this answer. I have also had this happen on questions and answers I have posted.

Has anyone else experienced this problem? What should I do about it?

I'm on the most recent version of Safari.

Edit: Following the advice of Martin Sleziak, I tried to replicate this bug in the non-default renderers (SVG and MathML). They both render integrals correctly. I conclude that this is a problem with the HTML-CSS renderer.

    $\begingroup$ Debug Check: Does not duplicate on latest chrome nor latest IE on a Win 7 SP1. Does not duplicate in safari on iphone with ios 6 for me. My pet bug is that on TeX edit in chrome the font is silly big, but a refresh always fixes this. Best of luck. Try isolating the bug to the browser brand. $\endgroup$

  • $\begingroup$ What is your choice in the MathJax menu under Math Settings/Math Renderer. Does it influence whether this bug appears? (See this image if you cannot find the menu.) $\endgroup$

    $\begingroup$ @GEdgar Right-click a piece of rendered MathJax, then follow the menus shown by Martin Sleziak above. $\endgroup$

Yes, I saw this too. Safari 7.0.1 on Mac OS 10.9. The first time I noticed it was yesterday.

  • $\begingroup$ On that answer, with the HTML-CSS renderer, Safari does that integral in the defective manner. Other integrals (even the same size, later in the same line) are OK. But yes, it is consistent with that particular integral. $\endgroup$

  • $\begingroup$ OK, I switched back to HTML-CSS, and the problem is gone for me. So, what has changed since Dec 23? $\endgroup$

  • $\begingroup$ Nothing that we're aware of. It may have been a cached file that was tripping things up for you. Let us know on the bug tracker if you run into this again. $\endgroup$

    $\begingroup$ @GEdgar I don't work for MathJax anymore. From the looks of it, stackexchange still uses MathJax v2.7.5 which is now over 4 years old (and woefully out of date - v4 is in alpha status right now). So you probably want to start by getting SE to update. $\endgroup$
