Research direction
Start by reproducing the issue on the listed Steam Machine with SteamOS 3.8: launch a game and trigger a Steam toast notification from a friend. Observe the 5–10 second freeze and subsequent 30fps lock, and compare behavior after restarting or waiting. Done means the cause is identified and the notification no longer produces the reported performance regression.
