Could you send the full output of xdpyinfo on your display, so we can see the details of all the visuals? I suspect nobody's tried xpopple on a 30-plane display before, and the code in XPDFCore::setupX either isn't finding the right visual or is computing the wrong masks. > xpdf home-page shows the latest version is 4.06 That's effectively a different project. xpdf 4 uses a Qt GUI and its own PDF code; Debian's xpdf is the xpopple Motif GUI with the Poppler library for PDF rendering (both of which were derived from xpdf 3 originally, but have been developed separately since). If Debian was to package xpdf 4 then it would need to be under a different name (i.e. xpdf4), but there doesn't seem to have been much interest in doing this so far; I guess people wanting a Qt PDF viewer are mostly using Okular.
