The PDF export requires to rasterise the various "reflection" layers on each droplet because of their Gaussian Blur Effect. This effect is not part of the PDF specifications for vector transparency.

How unfortunate. Thanks for clarifying.

Unfortunately nearly all Fx will cause export to become rasterized. Gaussian blur might stay vectorized (or can be forced to stay using an export setting), as can be outer shadow and glow. All the rest result in rasterization of output. Masked compositions often cause rasterizations in Affinity apps or might require specific compositions, and in combination of raster images, often also cause inadvertent upscaling. Using clipped constructions sometimes helps.

As a fix I had done something similar to what  you suggest. Strange behaviour of affinity to do this.

Lagarto, maybe I'm misunderstanding but is "blurrybug" meant as a blur example? If yes, I can't find any blur – Can you point me to it?

However e.g. radial transparencies will be exported non-rasterized to PDF as "smooth radial shadings" so these effects might to some extent be used instead of blurring.

Yes, in the case of the reflections, a white-to-transparent gradient would work here as well – though that would be a lot of work in this existing document. However, such gradients cannot replace all common use cases of blur effects, even if especially for vector objects a simulation with gradients can be used as a substitute.

"blurrybug" – ah,okay, so I was just mislead by the filename ;)

What would be the closest possible effect of a water drop that will not be rasterized? I would greatly appreciate a hack or suggestion.
