[Paraview] pvbatch (3.8.0) rendering through OSmesa does not work on multiple nodes

[Sven Buijssen]

Hi,

I've had the exact same problem last week with ParaView git/master on
Linux x86_64 with Mesa 7.8.2, having applied the patch you mentioned to
the Mesa 7.8.2 sources. (It's also the only patch present in the Mesa
git master for that particular bug,
https://bugs.freedesktop.org/show_bug.cgi?id=10966.)
Whenever I tried to save an animation from the ParaView client (builtin
mode), ParaView still crashed. I tried to avoid that by removing a
duplicate call of OSMesaMakeCurrent() from the VTK sources by means of

> diff --git a/Rendering/vtkXOpenGLRenderWindow.cxx b/Rendering/vtkXOpenGLRenderWindow.cxx
> index 5a87aae..493a3fb 100644

>        }
> -    this->MakeCurrent();
>      }
>    else

but that turned out to be not sufficient, OSMesaMakeCurrent() is still
called multiple times when ParaView git/master is trying to save an
animation.

I reverted to Mesa 7.5.2 to resolve the issue.

Hope this helps
Sven
