On Proton 11 (Beta), when trying to close Arc Raiders through the ingame menu, the game fails to fully close and I have seen have fossilize_repla processes that are unkillable. If there's any further information I need to gather, feel free to let me know.
I have used the following runtime options: PROTON_LOG=1 SDL_VIDEO_DRIVER=x11 PROTON_ENABLE_WAYLAND=1 PROTON_USE_NTSYNC=1 gamemoderun %command%. If some of these are unnecessary, feel free to let me know.
These zombie processes are visible upon launch:

These are the zombie processes that are visible once I close the game and the game is running according to Steam:

Even when I kill the parent processes that spawn the GameThread, the GameThread isn't reaped.
