[Paraview] Animation with sudden large intervals between consecutive frames

[Tom Fahner]

After some more diagnostics we found that the graphics card memory was full
during the large intervals. As we did not manage to monitor the graphics
card memory usage in normal operation, it is not entirely certain that this
is the cause, however since the normal memory was slowly being filled
during the large intervals this seems to be the main cause. I am wondering
if there are typical settings that we can modify in order to reduce the
graphics card memory footprint? If not, we should consider updating our
hardware I guess.
