It's a rendering bug that appears to be specific to -dev xcairo. -dev qtwidget does not have this problem, and neither does -dev svg. (For the latter, you must use the familying option -fam which will generate two files corresponding to the two pages.) An even more spectacular example of this xcairo bug is example 8. The first four pages look okay (since they duplicate each other in most respects), but then for pages 5 through 8, the page 4 plot gently fades away in the background as more and more partially transparent layers are added on top of it. Hazen, will you have a look at this issue, please? This transparent background issue does not appear for, e.g., -dev pscairo so it appears this issue may be specific within the cairo devices to just -dev xcairo although I haven't checked the other cairo device possibilities beside pscairo.
