Here’s the Twitter thread discussing this
Basically, some different apps were linked to the official steamVR app. These apps are hidden, but the data miner was able to grab some assets from them that included some custom art for Waydroid, which is a Linux program that lets you run Android apps on Linux.
Additionally, I’ve seen comments saying that some valve devs have been making pull requests for the Waydroid github, but I don’t actually have a proper source for that.
I see this as a win because if I could ever get Waydroid functioning properly, especially on a Steam Deck, I could more comfortably play the pvz2 mods I wanna play but can’t because android is too locked down for me to be able to move files where they need to go.
