SUMMARY I have some partitions in NTFS mounted with ntfs-3g, and thumbnails for at least mp4 and jpg files (didn't try other formats) don't work anymore. Thumbs in my ext4 partitions work as expected. STEPS TO REPRODUCE 1. Mount a NTFS drive with ntfs-3g 2. Place some JPG and/or MP4 files anywhere in the partition 3. Open with Dolphin the location where the files reside OBSERVED RESULT Thumbnails for files not being generated, I just get the standard multimedia Icon corresponding to the file format. EXPECTED RESULT The thumbnail for each file should show up. SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon 5.24 KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93 Qt Version: 5.15.3 ADDITIONAL INFORMATION I can't tell when this started happening since I've been out home for three months, when I started using my computer again I did all the updates and there's when it stoped working.
