I have experience with Runelite in a third party Jagex launcher project I worked on recently. I have learned that Runelite has a small launcher program that forks and launches another Java process that is running an embedded jar file. The problem is, steam only sees the first “launcher” and not the forked Java process. So once the you launch Runelite steam thinks you closed the game.

I would recommend finding the Runelite.jar file and launching that directly with Java ie. “java -jar Runelite.jar”.

Edit: I just checked, you can download the jar from the Runelite website (it’s at the bottom of the list)

I’m with you, I’ve switched all my computers to Linux for similar reasons. I bought an android phone recently and put Linux on that, although still some things to iron out such as sound and microphone input but it’s working well otherwise. Looking forward to when I can ditch my iPhone.
