[Paraview] [Non-DoD Source] XDMF crash

I already tried XPath pointers, but it takes a few seconds in ParaView when
I click to the next time frame ---
whereas it takes only 0.1s to change the color when I switch the Active
Variable for the ColorMap in ParaView's dropdown.
I thought using SubSet, ParaView might "recognize" that it is actually all
the same geometry.
But meanwhile I assume ParaView always thinks the geometry might change
between timeframes
and takes much time for switching between timeframes no matter what file
format I use.
