Running Jellyfin 10.9.10 and use Jellyfin Media Player 1.11.1-1-amd64-bookworm.deb, and just setup a computer, with KDE Plasma desktop envoirement, which means it uses Wayland. When using that, the Jellyfin Media Player is just a black window, so i reinstalled Debian 12.6, but with Cinnamon Desktop enovirement which uses Xorg - As far as i know. This makes me belive that there is an issue with KDE Plasma / Wayland on Debian 12.6.
