Sorry if this is not the correct forum to report a possible bug.
I noticed browsing the "Example of second-order singular perturbation theory" section of the "Perturbation Theory" page on wikipedia:
--- Consider the following equation for the unknown variable <math>x</math>:
:<math>x=1+\epsilon x^5.</math>
For the initial problem with <math>\epsilon=0</math>, the solution is <math>x_0=1</math>. For small <math>\epsilon</math> the lowest order approximation may be found by inserting the [[ansatz]]
:<math>x=x_0+\epsilon x_1 (+\cdots)</math> --
that the markup fonts of "x" in each of the :<math> sections are different. In particular there are no serifs on the top x's in the first equation and x_0=1 on my Linux box. On the others, there are small serifs.
I don't see why they should be rendering differently. The ascii certainly doesn't indicate anything to me...
I've tested this on: IE7.0 Windows Safari 4.0 on OSX 10.5 Firefox 3.5 on OSX 10.5 Firefox 3.0.10 on Linux 2.6.18-128.1.10.el5
I've attached a small screenshot of what I see.

All the math is displayed in a serif font for me (Chromium 3.0.192.0 (0) on Linux). Of course, since it's italics, they aren't standard "straight" serifs, but it's visibly a serif font nonetheless. Obviously, one of those math things is an image, not text, so that one looks different. All the equations are wrapped in <span class="texhtml">, which renders them in a serif font.

Ah, I should have looked at the page source, rather than just the wiki source. I am guessing that too-complicated math is TeX rendered into an image, but less complicated math is handled by the html?
Well, a quick lesson. Thanks.

Yes, by default. You can change it in your preferences (but some things will always have to be images, unless our MathML support actually works).

You can force it to render as an image by adding "\ " or "," http://en.wikipedia.org/wiki/Help:TeX#Forced_PNG_rendering
