Sometimes maths seems to have strange and squashed spacing, but the problem is intermittent. For example, this is what Fitting a fixed, exponential relationship between categories with categorical data looked like for a while on Chrome today: alt text http://robjhyndman.com/Untitled.png But a few minutes later it looked fine. Is this a known problem and is someone working on it?

    $\begingroup$ If I see this problem, then open the same page in firefox, followed by a refresh in chrome, the problem disappears. Is anyone from the SE team reading this? Can someone please fix it? $\endgroup$ – Rob Hyndman Aug 17 '10 at 1:41
  • $\begingroup$ @Jeff For me, all pc's with Ubuntu (9.10 and 10.10) and Chrome 7.0.517.41 always messes up the formula's. So I suggest trying a ubuntu live cd and install google-chrome for reproduction $\endgroup$ – Peter Smit Oct 26 '10 at 5:08
  • $\begingroup$ I was having the same problem with Chrome 7.0.517.41 on Ubuntu. I've just restarted the browser to pick up an update to 7.0.517.44, and the problem seems to have gone. $\endgroup$ – NPE Nov 10 '10 at 18:23

For me (Chrome 7.0.517.41 on Fedora 13) LaTeX inserts does not appear or appear in random places. On the same machine Firefox 3.6.10 manages to render it well.

  • $\begingroup$ Try Chrome 7.0.517.44; the update has fixed the problem for me. $\endgroup$ – NPE Nov 10 '10 at 20:41
  • $\begingroup$ Indeed, things got better after auto update; I forgot to write it here. $\endgroup$ – user88 Nov 11 '10 at 9:35

I see this problem with Chrome 14.0.835.186 on Ubuntu 11.04 (classic mode).

Today is the first time it has occurred, but when it did, only one of two uses of \sum() had smushed brackets (see below). The question Calculating likelihood from RMSE (I edited the first equation to \sum\left(...\right) thinking it would help, but it didn't).

    $\begingroup$ Notice the i beneath the $\Sigma$ in the first equation: it appears to be almost in the correct location with respect to the summand and clearly is shifted left of center. This suggests that the positioning algorithm thinks the $\Sigma$ is much smaller than it really is, but then rendered it at the correct size, fixing the bottom left corner position. The only apparent difference between the two "\sum" commands is that one of them initiates the $\TeX$ line and the other does not. $\endgroup$ – whuber Oct 7 '11 at 15:05

I can't reproduce this -- how do we reproduce this?

    $\begingroup$ I am seeing this problem with all formulae on the site. I am using Chrome 7.0.517.41 on Ubuntu 10.04. $\endgroup$ – NPE Nov 10 '10 at 13:34

I'm not getting any equations at the moment. I see the TeX code for a few seconds, then this (Firefox 3.6.3 on Windows XP):

alt text

A "Failed to load" message appears in the bottom left corner of the screen, but goes away before i have time to read or capture it. It was ok earlier today (i have restarted my PC since then though).

UPDATE: Just rebooted my PC as I was having another, apparently unrelated, internet problem too (failing to contact the proxy server). It fixed that problem, but not this TeX display one.

2ND UPDATE (Following morning): It's OK now.
