Latex Hyperref color rendering inconsistency

Currently, the zathura mupdf backend displays certain link colors (e.g. citations) generated by hyperref+pdflatex wrong. Generating the links with xelatex rids of the problem. The rendering issue does not occur with the poppler backend, okular, macOS preview and the mupdf binary application, so I'm quite sure there's something wrong with the mupdf backend. The problem occurs both when I build this library from source (I have tested the development branch paired with the newest libmupdf), and when I install it through pacman.

I've included a screenshot comparing okular versus zathura-mupdf rendering. (the issue is very odd as only one of the pages at maximum seems affected, the file shown in screenshot for example only has the color incoherency on the first page while the other pages are colored correctly)

If needed, I could send over the PDF and .tex file(s) with the rendering issue.
