    Starting here, you can read (interspersed with a conversation about math) a conversation between me and Dmitri Pavlov about how Dmitri cannot read the MathML on the Forum. He can read it just fine on the Lab. We potentially diagnose the problem as too wide pixel-based spacing in the Forum’s MathML CSS. Can anything be done about it? Screenshot.

    This is probably MathJaX, it’s almost certainly not iTeX. However, that’s by-the-by. What is “Chromium”? What machine is Dimitri using? The closest I have is Google Chrome on a Mac where it looks just fine. I need to be able to reproduce the problem to be able to have a chance at fixing it.

    Chromium is Google's browser. It is also known as Chrome when it comes with Google logo.

    I must admit that I can longer reproduce the problem myself, which probably means that MathJax was recently updated.

    However, I do see a problem on MathJax's home page http://www.mathjax.org/,
    where the LaTeX formula on the right is displayed with numerous overlaps, although not as severe as in the above screenshot.

    Changing the zoom level resolves the problem (overlaps disappear), but makes reading inconvenient.

    Inspection of the actual HTML code reveals that all distances are in em units, not in pixels, which in theory should mean they should display fine at any zoom level.

    Thus it might very well be a problem with Chromium's font handling and not with MathJax.

    This doesn’t make sense to me; surely it’s iTeX, because iTeX input is the pseudo-LaTeX that I used. It just rendered with MathJaX instead of with MathML, right?

    It seems like the page http://nforum.mathforge.org/discussion/3981/stacks-of-algebraic-ktheory-spectra-and-topological-ktheory/ has overlaps, which I can currently reproduce. For example, in Comment 2 by Mike Shulman the blackboard letter Z overlaps with "an".

    I don't really understand the point of iTeX. MathJax can render both MathML and TeX, why do we need iTeX at all?

    I get this problem using Opera mini on my phone (at the nforum and MO). For instance, comment 11 by Mike at the 'stacks of algebraic K-theory...' thread. Although the thread that Toby linked to originally is not even rendering; I get   and plain text instead of maths.

    That’s the false assumption in what I’ve just read. The process is the following:

    1. User inputs pseudo-LaTeX
    2. Server uses iTeX to convert that to MathML
    3. Server sends MathMl to client
    4. If client says, “Sorry, I don’t implement web standards”, server also sends MathJaX
    5. Client either natively renders MathML or uses MathJaX to convert it to some HTML+CSS and renders that instead

    So your funny display issues are due to MathJaX, not iTeX. It is possible that there is some interaction between the MathJaX CSS and the forum’s own CSS, but that’s nothing to do with iTeX.

    (Incidentally, with its Pseudo-LaTeX input, MathJaX also converts it to a form of MathML internally)

    There is a previous discussion of MathJax on the Forum that may be useful background.

    Regarding reproducing … I edited my comments on the positive cone thread to use HTML and Unicode directly, so Dmitri could read them without difficulty. But you won’t be able to reproduce anything there.
