Hello *,
The behavior of app-text/qpdfview has changed recently (approx. durung the
last week) in a mysterious way. qpdfview itself has not changed (the
revent -0.5_p1 is irrelevant - I'm discussing the stable version 0.5).
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

Are you sure that grayscale option is not enabled ?
View -> Convert to grayscale

That's it! I'm absolutely sure that I never enabled this option on
purpose. Probably, some accidental mouse click.
Sorry for the noise,
Andrey
