Mathjax / Latex rendering issues with formulas , spacing issue

[hugo]

Hi there,

Love your work really usefull, I have several jupyter notebooks that worj great render fine. Now I have some new ones that have issues with rendering the mathjax formulas. It seems the space after formula is indented so the text after the formula and the formula itself are printed over each other.

CLI output:

Strange thing is it is not happening all the time and even on one slide sometimes yes sometimes not...

ANalysis Of VAriance : ANOVA

Assumption:
$ \overline{X} $ follows a normal distribution with mean $ \mu $ and variance $ \frac{\sigma^2}{n} $

The ANOVA is based on the law of total variance, where the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical test of whether two or more population means are equal, and therefore ANOVA generalizes the t-test beyond two means.

the jupyter notebook renders fine the issue is when converting to PDF

[hugo]

decktape version 3.4.0

[Antonin Stefanutti]

It's possible that Decktape starts converting a slide to PDF while MathJax hasn't completed updating it.

I drafted a while back using MathJax signals, but it has to be revived, if that is the actual root cause of the issue.

That's why i added this option : --load-pause=20000 ? I will review your link asap

[Antonin Stefanutti]

That's why i added this option : --load-pause=20000 ?

The --load-pause option adds an initial delay, and I'm not sure that's enough to guarantee everything is loaded, depending on how RISE works. Maybe increasing the pause for each slide, with the --pause option, would help.

Another test that would help to identify the root cause would be to export screenshots, with the --screenshots option, and see if the issue also affects the image export.

Thanks for the --load-pause tip; that solved a problem I was facing (same error).
