Dolphin not Generating Thumbnails (Solved)

[uro]

Replying to provide additional info:

This is an upstream bug with KDE’s Oxygen theme, there is another recently closed thread reporting the same topic of thumbnails disappearing in Dolphin when the Oxygen theme was applied:

Thumbnails Dolphin disappeared

I cant see anything that stands out in the packages spec file as interfering with thumbnails. However, I checked on KDE’s bug portal and found a few issues reported there relating to thumbnails and Oxygen theme: https://bugs.kde.org/show_bug.cgi?id=504126 https://bugs.kde.org/show_bug.cgi?id=504913 and one semi-related but with no mention of Oxygen with this one: https://bugs.kde.org/show_bug.cgi?id=503799 Maybe some of those symptoms match with what you experienced with the plasma6-oxygen…
