[Paraview] "pseudo" random glyphs

[David E DeMarle]

Not sure if the way the seed points move around over time with time
varying data is a bug or a feature.

A work around is to use the glyph with custom source filter.

To make the custom source that you will use for the seed points, glyph
the first time step as you are doing now, but make sure the output
type is points. Save that output as a vtk polydata file.

Next read that file back in and use it as the source input the glyph
with custom source filter.

That is, randomly select the points to use, but then use the same points for each time step.  If I understand it correctly, not checking the Random Mode box causes paraview to just select the first N points.  In my case (probably most cases), this concentrates all of the glyphs in one region of the mesh.  Instead, I would like to randomly distribute the glyphs across the mesh, and using the Random Mode for this works fine for a single time step.  But if I want to animate a time series, I would like to show glyphs on the same points for each time time step, rather than have the glyphs jump all over the place.  Is there currently a way of doing this?
