Thanks for the report. The handling of the adaptive CSS was updated substantially in v3.2, and it looks like there is a spot where the adaptiveCSS setting wasn't being taken in to account.

Can you use adaptiveCSS: true for now? The performance of this is much better in v3.2, and since the full CSS has a large number of rules, that can cause performance problems (e.g., when zooming in and out). Just for my information, can you say why you have it set to false?

Setting adaptiveCSS: true is ok.

It was set to false because we tried to render math on some slow devices. If the css updates dynamically, the page will filcker when the browser reloads css.

If the css updates dynamically, the page will filcker when the browser reloads css.

The 3.2 release includes better handling of the CSS updates that should reduce or eliminate the flicker. Give it a try and see if that is an improvement for you.

Hello! I use MathJax.tex2chtml() in the markdown-it plugin to convert the math in markdown, not in html file, so I need a full CSS import to the final generated html.

@Eumeryx, if you do multiple MathJax.tex2chtml() calls and then get the CSS via MathJax.chtmlStylesheet(), it will include everything needed for all the calls you have made up to that point, so you should not need the complete CSS.
