MarsSeed [1] filed a deletion request for poppler-lcdfilter [2]: This patch to poppler has been discontinued since 2018, because starting from poppler version > 0.43, it did not work, as per maintainer's comment.
Users should just use extra/poppler. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/poppler-lcdfilter/
