Description Patrick Gianelli 2025-03-22 20:13:50 UTC 
SUMMARY
Prior too 6.12, folder previews displayed normally for SMB shares. Updating to 6.12, previews do not show. NFS shares continue to function normally.

STEPS TO REPRODUCE
1. Check "show previews for folders" in settings in Dolphin
2. Set file preview size to some large number (1GB)
3. Mount a SMB share, eg: sudo mount -t cifs -o credentials=/home/user/.creds,uid=user,exec,mfsymlinks //192.168.1.10/Share /mnt/Share/
4. Create a folder.
5. Put photos in the folder

OBSERVED RESULT
Folder shows with no previews on it. File thumbnails function normally.

NFS shares continue to work normally.

EXPECTED RESULT
Folder previews work.
