That's very possible, occasionally I install things from experimental. I
don't remember explicitely installing mesa 6.5.3, but perhaps apt
remembered a former install from experimental.

Thanks for locating and forwarding the bug. The specific problem seems
to be that the darkening of the shadows is applied to the whole polygon
and not only the stencilled area (there are still different levels of
darkening depending on the orientation of the polygon).
