particle size in paraview screenshot

couldn't find anything in a search

in paraview, I use the liggghts reader and the point sprite plugin to visualize my solutions, because that saves a ton of computer resources compared to using a glyph.

i frequently save screenshots for papers, presentations, etc. when I save a screenshot at the default image size (approx 1000x700 on my machine), everything looks as it should. if I try to save a screenshot at a larger size (say, 4000x3000), the point sprites seem scale with the image size, i.e., get bigger. this happens whether I scale the particles by the radius transfer function, or by a constant value (all of my particles are the same size).

is this a "feature" of the point sprite plugin? saving screenshots with spherical glyphs don't behave this way, but with larger simulations, the extreme memory requirements can cause my computer to crash, so that's not always a viable option.
