Since updating to MacTeX 2011, I have a font kerning problem when using xelatex with beamer and the fontspec package; the spacing in mathematical formulas is off, so letters collide with parentheses and text decorations.
Here is a minimal example: --------- %!TEX TS-program = xelatex %!TEX encoding = UTF-8 Unicode \documentclass{beamer} \usepackage[no-math]{fontspec} \usepackage{xunicode} \usepackage{xltxtra} \begin{document} \begin{frame} $f(x)$ and $y'$ \end{frame} \end{document} --------- When the three \usepackage commands are commented out, the spacing is fine; with the three packages, the f runs into the left parenthesis and the prime touches the letter y. Am I missing some option when calling the packages? Any help is appreciated!
