The image shows the small dots produced when exporting a drawing to PDF. I highlighted some of the dots, but left the rest as they were.
When you export to PDF a document containing a drawing, extra dots are produced. This is most visible when the drawing includes round or oval elements.
Steps to reproduce:
1. Prepare a document; I used Writer for this
2. Include a drawing that has some round elements
3. Export the document to PDF
4. Open it with Acroread.
Small dots are seen at the upper left and lower right corners of the round element.
No dots should appear.
Operating System: openSUSE
