This is really a duplicate of bug 423544 which is about a supported component and was closed by mistake.
Seems it works for regular thumbnails, but the preview panel ignores it. Is this what you are experiencing too? dolphin 25.03.70 Operating System: Fedora Linux 41 KDE Plasma Version: 6.2.80 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.0 Kernel Version: 6.11.8-300.fc41.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15,5 GiB of RAM Graphics Processor: AMD Radeon RX 6600
This report is about the regular thumbnails, and currently I'm unable to reproduce the reported issue. But I can confirm that the preview panel ignores the setting. Operating System: Arch Linux KDE Plasma Version: 6.2.3 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.0 Graphics Platform: Wayland
Alright, if you can't get the issue anymore I think we can close this. The preview panel showing thumbnails even with this setting works as intended. Thanks for the report!
