I was 16 hours into a Kino game, paused the game for brb, and the game closed on its own after like, 10 minutes of afk. No error popup or crash, I just saw the game close itself from a few meters away. I've looked for logs and can't find anything post-mortem: no Plutonium crash dump/minidump in the prefix, and nothing obvious in journalctl.

Also worth mentioning, I had this game going since a few a days already, and had had sessions and breaks like this one a few times already (as I used to do at least on windows on the standalone bo1 years ago).

Setup: 7.1.8-arch1-3, Hyprland/Wayland 0.56.2, 4090, latest GE-Proton, plutonium.exe added as a non-Steam game.

Launch options:
DXVK_FRAME_RATE=250 DXVK_ASYNC=1 PROTON_NO_FSYNC=1 PROTON_ENABLE_WAYLAND=1 PROTON_NO_ESYNC=1 %command%

Is this a known thing? Idle/pause-menu specific, one of these env vars, or something else? And is there anywhere else I should be looking for logs so I actually catch it next time?
