We've stumbled upon the same issue. The most recent versions of OSMesa crash when making multiple calls to MakeCurrent as they will attempt to create a new render buffer each time. As Sven mentioned, it has been reported to the Mesa Community. You can view our own findings related to this issue in these VTK and ParaView bugs.<div>

Hi,<br>
<br>
I've had the exact same problem last week with ParaView git/master on<br>
Linux x86_64 with Mesa 7.8.2, having applied the patch you mentioned to<br>
the Mesa 7.8.2 sources. (It's also the only patch present in the Mesa<br>
git master for that particular bug,<br>
<a href="https://bugs.freedesktop.org/show_bug.cgi?id=10966" target="_blank">https://bugs.freedesktop.org/show_bug.cgi?id=10966</a>.)<br>
Whenever I tried to save an animation from the ParaView client (builtin<br>
mode), ParaView still crashed. I tried to avoid that by removing a<br>
duplicate call of OSMesaMakeCurrent() from the VTK sources by means of<br>
<br>
> diff --git a/Rendering/vtkXOpenGLRenderWindow.cxx b/Rendering/vtkXOpenGLRenderWindow.cxx<br>
> index 5a87aae..493a3fb 100644<br>

<br>
but that turned out to be not sufficient, OSMesaMakeCurrent() is still<br>
called multiple times when ParaView git/master is trying to save an<br>
animation.<br>
<br>
I reverted to Mesa 7.5.2 to resolve the issue.<br>
<br>
Hope this helps<br>
