The Qt 6.7 problem is an issue where xdg-open inherits the environment of the Plex app causing kde-open to try to load the Qt 6.6 libraries from /opt/plex-desktop/lib due to the LD_LIBRARY_PATH set in Plex.sh.

This can be solved by editing the RUNPATH of the binaries using chrpath then removing the LD_LIBRARY_PATH line from Plex.sh. It turns out The main Plex library has a working RUNPATH but includes a bunch of automation cruft. The transcoding binary does NOT have it set, and QtWebEngineProcess needs no changes. In /opt/plex-desktop/bin run:

chrpath -r '$ORIGIN/../lib' Plex
chrpath -r '$ORIGIN/../lib' Plex\ Transcoder

However, this only exposes additional issues with all of the Qt environment variables set in this script. I couldn't find a super clean way to fix this, but interestingly enough KDE uses a little utility for their AppImage deployments to deal with this exact problem:

Compile it and copy the exec.so file into /opt/plex-desktop/lib then alter Plex.sh like this:

This could even allow using LD_LIBRARY_PATH and not using chrpath. The choice is yours. Using chrpath seems cleaner but pulls in a dependency.

In case anyone has the same issue as me if you want to control UI scaling you can use the QT_SCALE_FACTOR environment variable. (0.75, 1.0, 1.25, etc.)
