Hello @KrisCris, this is an issue with the Steam client, not SteamOS as a platform, so I've transferred this issue report.
Hey @kisak-valve, I just saw you renamed the issue, sorry for the confusion. Yeah, it's always nice to have thumbnails, but as they are non-steam apps, I am unsure if we want to sync them.
Actually, I am looking for a way to hide these icons or put them in a separate category.
Or, is there a way to disable a device to be streamable? like I only want to stream from PC to the deck, not the opposite way.
Nothing extracted yet.
Right now these non-steam apps from another steam deck occupy the non-steam app category, I hope there will be a better way to display them.
