[vtkusers] Assemblies "coming apart " during long test runs....

[Richard Frank]

So far it happens on all three of our machines ( Clevo "laptop" with quadro k5000m , I power computer with geoforce 9xx and another workstation with quadro m5000) , but it does seem low level as per flash/ recovery as you say...

Anyone from Nvidia on this list who might be able to assist? :-)

Thanks 

Rick

During a long ( multiple hours ) automated test, where a surgical instrument is moved through the scene repeatedly ( Made from implicit function sources and also combined into an assembly) , there is an issue - and the best way for me to describe it is that the assemblies " come apart.  Each actor in the assembly is moved to a deferent place in the scene, as if perhaps they " exploded ". We have videoed this and there seems to be a screen flash before the happens.
