# Remove MathJax Flicker in JSXGraph - processed using Mathjax

## Now using MathJax processing

This example shows how you can reduce MathJax flicker when user input changes some of the values.

Summary of the technique:

- On page load, hide MathJax math until it is fully processed, using the "End Typeset" signal
- On user input where values are changed (by dragging), hide the MathJax math again, by showing a "Processing..." message.
- Also, hide the MathJax preview using
`.MathJax_Preview{display:none}`

. (The MathJax documentation says you can stop the previews from appearing by using`preview:"none"`

in the configuration, but this didn't work for me.) - You need to use
`board.suspendUpdate()`

to prevent the text updating while the user drags. `board.mode`

has value 1 when an object is being dragged, 0 otherwise.- Show the math on mouse "up".
- If the user pauses while dragging, a timer fires the Update event and the math shows.
