[Mesa-dev] multiple versions in version string

[Gustaw Smolarczyk]

Isn't that version because it uses indirect rendering? AFAIK indirect
limits GL version to 1.4. There is the version of X's AIGLX driver in
parentheses, but only 1.4 features can be used.

But it may not be the case here. Could you check wheter glxinfo says
that direct rendering is enabled?
