If i am playing a Movie or TV Show via Kodi on my Steam Deck and put it into sleep mode, upon waking it up Kodi will completely freeze, No matter if the running Video is Paused or Unpaused and the only way out is by exiting with the Steam Overlay. I much prefer to use Kodi because i was yearning for a All-In-One Multimedia app for my Steam Deck to use it on both its Handheld Screen and dock it up to my Non-Smart TV.
Using the Flatpak Edition of Kodi
