BTRFS qgroups warning/error

when I shutdown my computer I will get an BTRFS error. Any idea how I can get rid of it? What does this error mean in detail? The computer is running fine in general. To Google this error has not helped at all.

System is current Manjaro with full disk encryption and (obviously) BTRFS. I am using Timeshift for snapshot creation.

BTRFS warning (device dm-0): qgroup 0/256 has unreleased space, type 0 rsv 16384
BTRFS error (device dm-0): qgroup reserved space leaked

Some output that might help. Is other information needed?

I suggest disabling quotas. There are reported problems with quotas. :sunglasses:
