qBittorrent & operating system versions

Qbittorrent v4.6.2 appimage
OS: Ubuntu 22.04 6.5.0-14-generic

What is the problem?

sqlite database becomes partially corrupted after unclean shutdown, even with "save resume data interval" set.

Steps to reproduce

Run QBT
add a bunch of stuff
wait 2 hours (or whatever your save interval is) plus one minute
have an unclean shutdown
missing torrents

Additional context

After the unclean shutdown I was missing a bunch of stuff that had been added after a certain date (literal days, dozens of files). I vacuumed and pragma_check'd the database file. File lost about 8% of its size. relaunched QBT and some of the missing content was restored.

Does QBT need better handling of the sqlite file, or for it to internally do periodic checks?
