Whenever I enter LaTeX formatted questions and answers on sites such as Math.SE and CSTheory.SE, the region that dynamically displays the formatted text below the text-box. This is a wonderful feature. However, it updates with every keystroke. The time necessary to render/format the LaTeX is slow enough that the text is first displayed unformatted, then within roughly half a second, the formatted text is displayed.
Since the size of the unformatted and formatted text are significantly different, this leads to a very jarring, disruptive appearance. Every keystroke, the text changes back and forth between the two wildly different formats.
A couple of possible solutions:
Optimal: Only display the formatted text if no new text was received in the last ~2 seconds.
Simpler: Add a toggle checkbox to temporarily turn off LaTeX display.
With the bounty running out after a week, is it correct to assume this is not easily fixable?
