No, but it looks like the problem is that PMS now includes the iHD VAAPI Driver from the Intel Media SDK on Linux and it doesn’t seem to work with Gemini Lake yet (at least not in the version they are shipping).
In theory adding a systemd unit override to set the LIBVA_DRIVER_NAME=i965 should work to make Plex Transcoder use the old i965 driver, but in practice this doesn’t work.
What worked for me on 1.18.2.2041 was to rename the iHD driver:
mv /usr/lib/plexmediaserver/lib/dri/iHD_drv_video.{so,bak}
systemctl restart plexmediaserver
After that hardware transcoding works again and is using the i965 driver.
