Nope, tried all that.  I think it's some type of bug because the cameras zoom affects the result, as well as the position.

I can't upload a project file at the moment but I will when I get the opportunity (it's only 28k).  Hopefully someone will identify an obvious thing I have overlooked.

The only unusual aspect of the project is that there is a world transformation that slowly rotates the y axis.  I think there's a bug that mis-calculates the distance from a particle to the camera when the world transformation is animated.

Could they be popping behind the camera?   Try moving your camera back and zooming in, or something similar, like moving the producer back in Z.
