SUMMARY My disk setup: a single NVME drive with several logical volumes created by LVM, each with their own LUKS container. They can be unlocked as needed, similar use case to vaults or gocrypfts etc. ~/home is on a specific volume (e.g. xfs partition on an unlocked /dev/mapper/luks-vg-home) ~/home/thing may be a different volume (e.g. xfs partition on /dev/mapper/luks-vg-thing) The only thumbnails that end up in ~/.cache/thumbnails are for files on the same filesystem as ~/home. In the above example, any thumbnails in ~/home/thing are regenerated every time. I believe this changed in the last couple months, and before that it actually did cache everything as expected. STEPS TO REPRODUCE 1. Mount $HOME from xfs filesystem on LUKS container A 2. Mount some other $HOME/thing from xfs filesystem on LUKS container B 3. Browse files with Dolphin OBSERVED RESULT - Dolphin caches thumbnails for files from any encrypted filesystem EXPECTED RESULT - Dolphin caches thumbnails only for files in the encrypted filesystem that $HOME is on SOFTWARE/OS VERSIONS Linux/KDE Plasma: arch linux KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 ADDITIONAL INFORMATION
