Hi - I can reproduce on my Fedora KDE 42 device by creating a TIFF file from an existing image. Thanks!

Moving to kio-extras since it appears to be more generally an issue with thumbnailing (ex. this also occurs in open/save dialogs), sorry if that's the wrong place!

Seems tiff was left out from https://invent.kde.org/network/kio-extras/-/commit/a0e621b7153c9fcb4f5d5e9dda6223948bf83a6a for some reason

Installing kdegraphics-thumbnailers is a better solution.
Comment 8 Patrick Silva 2025-05-02 17:10:11 UTC 
kdegraphics-thumbnailers 25.04.0-1 package is installed on my system and there is no preview for .tif files.
Comment 9 Junakreiter 2025-05-03 06:41:00 UTC 
Can this problem be solved ?
Feels like beeing blind...
Comment 10 Kai Uwe Broulik 2025-05-03 06:47:05 UTC 
Wait for 25.04.1, it will have the aforementioned fix.
