[Paraview] particle tracking

[Christian Richter]

Hi, Utkarsh,

sorry I forgot to replay to the list. I wrote Marcelo yesterday
"Dear Marcelo,

try Edit->Settings->Render View and disable "Use Offscreenrendering for 
Screenshots".
The animation will take more time, but the memory ussage is constant low.
We have the same problem when proccessing a large number of timesteps in 
PV 3.12.

Best wishes,
Christian "

And he said now it's working fine.

But in fact, this does not solve the real problem.
I have a GTX580 GPU with NVIDIA 290.10 64bit proprietär driver and the 
same memory leak when proccessing a large number of files (>200 by 
fileseriesreader->vtkreader or my own liggghts plugin reader).

Can you please tell me how to check if OSMesa is used or not and how to 
track down where the memory leak comes from (it is not the reader) ?

Thanks,
Christian
