Minimal test file: \documentclass[a4paper]{foils} \usepackage{amsmath} \usepackage[darkbackground,colormath,,coloremph,colorhighlight,fixcolorstack]{texpower}
\begin{document} This empty page causes the colorstack problem... Remove it and everything is fine \newpage Equation 1: \parstepwise{% \begin{align} \step{X} & = \step{Y}\\ \step{Z} & = \step{X} \end{align} } Equation 2: \parstepwise{% \begin{equation} \label{eq:1} \step{x=\step{\step{y+z+{}}z^2}} \end{equation} } \end{document} Error: The colors get all crazy. I'm sorry I couldn't make a smaller test file.
