Feathered shape does not export to PDF

[Noel Williams]

Many thanks for your suggestion. I've had to try another approach because I only want the feather effect to be visible on the inside edge.

I've moved the coloured block inside the page area, removed feathering and replaced it with transparency applied to the inside edge.
However, when I export to PDF I get a blank page.

This is a very simple feature which surely should work.

Any other suggestions welcomed.
