Sorry, I have almost no time to help with poppler rendering issues on Debian Stable.
Could you try with Debian Testing (or Unstable) which has poppler 24.08 (August 2024)? You could use a virtual machine to not disrupt your existing Debian Stable install. If the bug still exists there, please report the issue upstream: https://gitlab.freedesktop.org/poppler/poppler/-/issues Thank you, Jeremy Bícha
