 +''snapper-cleanup.timer'' runs every 24h from system boot. It cause lots of lagging on GUI, mainly due to very slow writes to ''/tmp''.

 +<code bash>
 +systemctl edit snapper-cleanup.timer

 +While Btrfs qgroups are considered stable for general use, enabling qgroups, especially in environments with frequent creation of large numbers of snapshots, can still lead to **performance degradation**, particularly during **snapshot deletion**. Qgroup accounting introduces additional metadata overhead and may affect system responsiveness under high-intensity snapshot workloads.
