Update to my previous comment ... running fstrim on 4.15.0-58-generic result in much more reported trimmed data (206.6 GiB) vs 4.15.0-55-generic (144.4 GiB) (e.g. this was not caused by snapshot release). On 4.15.0-58-generic I see errors like this in kernel log:

BTRFS warning (device dm-0): failed to trim 307 block group(s), last error -512
BTRFS warning (device dm-0): failed to trim 1 device(s), last error -512

Scrub finished with not problems so data on disk are fine (yeah!).
