Hello,
I'm having a problem with Publisher: when I export my 102-page document, made up of boxes and blank comic bubbles, as a PDF, some of the bubbles appear black. The bug also seems to occur directly in the preview, even though the bubbles all have the same background.
I tried changing the colour of the bubble in question to a colour other than white and the result was the same.
The solution was to rasterise all the pages but I'd like to know if there's a way to avoid this and understand what's happening.
(I'll add a clarification after a few tries: the bubble seems to take the colour of the edge, so if the edge is red the whole bubble is red).
Thanks for your suggestions
