I’ve now determined that it’s not just non steam games, it appears the Decky <-> SteamGridDB plugin is not working as it should. I’ve restarted / reinstalled both a number of times now, but it just spins while trying to load up any images. The manage screen does actually work, so I may just hang on to the plugin for that reason alone, since manually doing it through each screen in Steam is painful.
