[Paraview] pvbatch is not working with newer osmesa releases

[burlen]

Hi All,

pvbatch is not working with os mesa. however there's no issue when 
running pvserver in cs mode with same os mesa. so same operations 
initiated from a pvbatch script and from the gui in cs mode produce 
quite different results. Similarly, valgrind spews pages of unitialzed 
value errors (originating from mesa threads) when using pvbatch but not 
pvserver.

I'm using mesa from git, the issue was not present in mesa 
7.10.1....it's still very curious that things run fine using pvserver in 
cs mode and not in pvbatch... Any idea what's going wrong here? What 
does pvbatch do differently than pvserver that could account for the issue?

I'm attaching a python script and the images it produced with pvserver 
in cs mode and pvbatch.

You could also find this on the dashboards that use pvbatch and recent mesa
