# Insufficient space following MathJax, but only right after posting

I am using Safari 12.0.2 on macOS Mojave. In my answer https://mathoverflow.net/a/331026 , I see the following:

It seems to me that the spacing between the second and third parentheses at the end of (and then define $\lambda(p, t) = e(p(t))$) (on the first line of the screenshot) and between the first and second parentheses at the end of (1/2)\cdot(\tr(A) + \sqrt{\tr(A)^2 + 4\det(A)}) (in the first line of the displayed equation) is too small; in the second case this might be a matter of opinion, but in the first case that third parenthesis is almost invisible.

Interestingly, the problem seems to appear only immediately after the post. Here's what the post looked like to me immediately after an edit:

and then, after refreshing (with no other change):

Notice the changed spacing.

• On my system (Microsoft Edge 44.17763.1.0 on Windows 10), the parentheses display correctly. May 8, 2019 at 9:19
• I just refreshed, and … it's now also fine on mine. That this really occurred is indicated by the screenshot, but I can't reproduce it, so should this be closed? May 8, 2019 at 9:20
• I do not know the correct terminology - but when MathJax is displayed I usually see "preview version" first and then the final version. (I am on Google Chrome. I have MathJax Renderer chosen as html-css with fast preview on.) The preview version seems similar to your first screenshot, although it is not the same: i.stack.imgur.com/9zpCt.png The final version looks perfectly ok. (Perhaps mentioning your MathJax settings - at least the choice of MathJax renderer - might help somebody to reproduce the same problem.) May 8, 2019 at 9:31
• The bug just recurred when I edited and again went away when I refreshed, but it's definitely an issue with the rendering of the final version. My MathJax renderer is HTML-CSS. May 8, 2019 at 9:34
• Yes, I have noticed this. HTML-CSS. But if I reload the page, the spacing is correct, so I do not worry about it. May 8, 2019 at 11:55
• @GeraldEdgar, indeed, from the user's point of view it's fixed by a refresh, so I now agree it's not worrisome; but, from the programmer's point of view, surely one would like to know why this problem occurs, even transiently …. May 8, 2019 at 12:11
• If you are talking about the programmer's point of view, perhaps the mathjax site is a better place for the question. May 8, 2019 at 12:18
• @GeraldEdgar, probably the comments aren't the place for an extended discussion of this; but, according to meta.mathoverflow.net/questions/1787/… , MMO is a reasonable place for MathJax bug reports. May 8, 2019 at 12:35
