[Paraview] Out of memory when exporting animations

[Thomas Witkowski]

I had also success with using the 3.8 version. BUT, I think, this is  
just a mere chance. In my case, the both versions, 3.8 and 3.10, seem  
to be compiled against totally different libraries, especially OpenGL.  
The 3.8 Version makes use of the NVIDIA OpenGL driver (there is also  
an nvidia gpu to be used), whereas the 3.10 seems to make use of the  
software OpenGL (not the mesa libraries). As I have no root access to  
the system I cannot try to recompile the 3.10 version.

Utkarsh, to reproduce the scenario is quite simple: I have a bunch of  
vtu files, one pvd file links to them. When stepping through the  
timesteps, the memory usage of the remote x server increases.
