For what it’s worth, in recent months Dolby Vision and HD Audio formats became viable on x86-64 hardware running Kodi (LibreElec, specifically):

I run Deluge for the same reason. AutoRemovePlus plugin and a couple others go a long way and just like Transmission it has a web-ui for remote management, so I can VPN back to my home network and manage deluge from my phone’s browser.

Have you tried toggling the HDR setting, saving the change, then toggling it back? It’s possible the update overwrote the setting you had without changing the setting in the UI.

I am also really worried they’re going to start making things “touch friendly” now… And we’re going to end up with the MacOS equivalent of Windows 8.

You mean iPadOS?
