MarsSeed [1] filed a deletion request for poppler-lcd [2]: Orphan. Modded variant of repo package poppler from 2 years ago. The custom patches for LCD subixel rendering have been abandoned since 2021. This feature would be of marginal usefulness in this day and age, since even 'just' FullHD (1080p) screens have enough pixel density that properly pixel-hinted (but not subpixel-hinted) font rendering can create crisp-looking text. Subpixel rendering is also tricky, because there is a myriad variety of LCD subpixel arrangements, and the algorithm should be prepared to support the actual one that the users's screen has, and it has to be configurable, otherwise the whole endeavor makes no sense and just worsens the rendered output. Though Qt5/6 poppler renders in worse quality than the base poppler package with gtk/cairo backend, that has nothing to do with subpixel rendering, and more to do with poppler maintainer's unwillingness to support cairo backend for poppler-qt for somewhat questionable reasons (fear of bugs, but he is hostile to anyone else willing to help out with contributing to and improving the Qt code for cairo).
