I'm sorry to report that the 1.22.1 fix has been reported to still be broken. I've removed all the bits from the release. If you have already downloaded it, please revert back to 1.22.0. You may need to reboot after reverting. Check for the issue with this command:

❯ rdctl shell df -h /var/lib
Filesystem                Size      Used Available Use% Mounted on
/dev/disk/by-label/data-volume
                         97.9G      1.3G     91.6G   1% /mnt/data

If the Size is less than the size 10G, then you need to do the reboot because the broken instance is lingering in memory. A broken setup looks like this:

❯ rdctl shell df -h /var/lib
Filesystem                Size      Used Available Use% Mounted on
tmpfs                     2.9G      1.7G      1.2G  59% /

In that configuration you will quickly run out of memory, and not of your images will be saved when you exit the application. I'm really sorry that this hasn't been caught sooner.
