Description Suyunbek 2026-02-10 06:30:10 UTC

Dolphin app freezes as soon as I copy file/folder and quickly becomes not responding after a while (30-60 seconds) it responds
I recently installed kubuntu with btrfs file system

File picker is also taking a lot to open
I'm using btrfs assistant and snapper for daily snapshots (not hourly)

here's my fstab
