Description David Karlsson 2022-05-08 19:20:32 UTC 
SUMMARY
 I am using Dolphin under WSLg (with Windows 11) and have a filesystem mounted with drvfs (9p).
And while Dolphin is generating the video thumbnails as it should, none of them are cached under ~/.cache/thumbnails.
Caching is working as normal on the root filesystem.
(I'm assuming this is handled by ffmpegthumbs, but it could be Dolphin too).

Fully updated Arch, with KDE Plasma 5.24.5 and KDE Gear 22.04 running under WSLg.

STEPS TO REPRODUCE
1.  Mount filesystem with drvfs.
2. Browse filesystem with Dolphin.
3. Find video files and wait for thumbnails to generate.
4. Look for cached thumbnails under ~/.cache/thumbnails/.

OBSERVED RESULT
~/.cache/thumbnails/ is empty except for folders like normal, large, x-large. (Assuming it was emptied before browsing).

EXPECTED RESULT
There should be cached thumbnails in the folders.

SOFTWARE/OS VERSIONS
Windows:  Windows 11 with WSL/WSLg
Linux/KDE Plasma:  Arch Linux
KDE Plasma Version:  5.24.5
KDE Frameworks Version:  5.93.0
Qt Version: idk, the latest one
