Until recently, qpdfview displayed color pdf files as expected - in color. Now it displays them as black-and-white (more exactly, as levels of grey). The source of qpdfview itself has not changed - it's the same version 0.5 which worked fine a week ago. So, it's the result of an upgrade of some library on which it depends. It depends on a number of Qt5 libraries (some of them were upgraded recently); on mesa (indirectly); on poppler; and on some things which don't seem relevant for the color/black-and-white issue. At the moment I have no idea where to start investigating the problem. Just to check: xpdf, mupdf, gv, zathura display these color pdf files correctly, in color. They depend on many of the same libraries; if some of the recently upgraded libraries suddently has become broken, this does not influence these other pdf viewers. Any ideas where to start investigating what has become broken? Thanks in advance, Andrey
