Jellyfin Media Player 1.12.0 — the first minute without a single click

How we tested: a clean Debian 13 in a disposable container; source — official file https://github.com/jellyfin/jellyfin-desktop/releases/download/v1.12.0/jellyfin-media-player_1.12.0-trixie.deb (jellyfin-media-player 1.12.0+deb). Run as a regular user on a virtual screen, 60 seconds, nothing clicked. 18.10.2026. Every network request and every file written was recorded; the code was not decompiled. The container was deleted afterwards.
