I see the problem.

It appears that Cairo doesn't know how to export tilings to eps except to rasterize them.  In fact, I'm not sure if Postscript defines vectorial tiling patterns at all.

Until five years ago, Ipe produced Postscript output itself instead of rendering through Cairo.   At that time, tilings and transparency were simply forbidden in EPS output.

Do you really need to use EPS?   Most publishers have switched to production based on pdflatex, and handle PDF figures very well.

Cheers,
