That may be a font issue. My preferred font is Linux Libertine, and as you can 
see in the attached image, things look a bit different: the accents on b are 
shifted slightly to the right so that they do not cross the ascender of the b. 
Compare with p, where the accents are placed more centrally over the letter.

This is the file that produces the attached output:

\documentclass[page=a4]{scrartcl}

\usepackage{fontspec}
\setmainfont[Mapping=tex-text]{Linux Libertine O}
\setsansfont[Mapping=tex-text]{Linux Biolinum O}

\begin{document}

b̃a b̂a

p̃a p̂a

\end{document}

Have you checked the output of the TeX command with `C-c C-l` to see if there's 
a more informative message? I've been using XeLaTeX for so long that I don't 
remember if there's anything special I needed to configure. All I know is that 
I have `TeX-engine` set to `xetex`.
