Next Generation Application Management
summary
Desktop now groups processes by kernel control groups so Plasma 5.19 tags every launched app into its own cgroups instead of guessing from windows — for example Discord in a Flatpak spawns 13 processes, which used to break accounting. The implementation uses the systemd user instance with scopes and optional services, adds metadata for fair/unfair CPU weights and OOM hints, includes a small demo that implements a foreground booster to raise focused-app CPU priority, and is rolling out behind flags while edge cases are fixed.
