the Oct 30 one doesn’t play them, the 27 one does. also whole lotta fucked up UI glitches, doesn’t respect the tv and desktop launch flags, some major changes afoot.


The Qt 6.11 update quietly made a decent number of breaking changes and a good amount of apps (including the old Jellyfin Desktop app in this case) that have simply had the dependency version bumped on them have encountered a variety of breakages,
Something that might also be happening is that there are genuine patches in
masterbranch for use with Qt 6.11, but the Flathub package is not pulling them as it is still tagged againstv2.0.0. Seems either a proper release should really be tagged upstream or the Qt 6.11 bump patch should have never made it to public on the Flathub package.
