Created attachment 95678 [details] Simple C-code to demonstrate the reported issue We have had persistent problems with thin "gaps" appearing between two adjacent fill areas that share a common, long, straight boundary. A snapshot and a simple program to reproduce the problem are attached. The issue occurs persistently with the document-type backends, i.e., PDF, PS, SVG. It also occurs for the image surface as well, but can be eliminated by turning antialiasing off. This has been observed for many versions of cairo over the past few years. We have undertaken a number of work-arounds, with various levels of success, but ultimately as seen by the test program, I think its fair to say this graphic artifact should not be present.
