Package: xpdf
Version: 3.04+git20250304-1+b1
Severity: important

Hello,

I have been using xpdf to read PDF files for decades. However, after
upgrading my monitor to 4k display with wider color-gamut, started Xorg
with 30-bit color depth (DefaultDepth 30 in '/etc/X11/xorg.conf').
'xdpyinfo' also reports:
depth of root window:    30 planes

Most of the other softwares I use displays without any problem.
However, 'xpdf FILE.pdf' only shows a Black page where the document
pages are supposed to show up.
Given that most of the present era monitors support 10-bit colour for
R/G/B, more and more people are going to be hit by this bug.
Therefore, I marked it as 'important'.

I checked for an updated version.
xpdf home-page (https://www.xpdfreader.com) shows the latest version is
4.06, which I download for Linux 64-bit, and installed as an user in my
home-directory.
It displays pdf files on my 30-bit display without any issue.
Therefore, updated xpdfreader works fine. However, all versions of
Debian is still using xpdf release 3.04.

Hence, to fix this problem, I suggest Debian xpdf package maintainer to
backport xpdf-4.06 through its source-code for Stable and Testing
version of Debian. Also, please upload the latest source-code (Open
Source) with necessary modifications in Unstable, so that it then
propagtes to Testing in due course.
