Environment:

Distro: Arch Linux
Desktop: KDE Plasma (Wayland session)
GPU: RTX 5070, driver 610.57.04 (open kernel module)
Steam client: beta, buildid: 1786661881 / 1786491548
Launch flags: -pipewire

Steps to reproduce:

Launch Steam with -pipewire on a Wayland/KDE session
Launch a game remotely (log has Abiotic Factor in it, and it happens across multiple games, not just one, also done via streaming)
Quit the game normally
Steam UI continues to show the game as "Running"
ps aux shows zombie processes that were never reaped

killing the main Steam process is the only way to clear the zombies, and a plain "Stop" from the UI doesn't work

ps.log
stream.log
