--- Comment #1 from Jan Rathmann <jan.rathm...@gmx.de> --- Hypothesis after investigating a bit (I hope it's not totally wrong): * Recently, the camera RAW images plugin has been added to KImageFormats (source: changelog of frameworks 5.99): https://invent.kde.org/frameworks/kimageformats/-/commit/eefb8146d360879e85c5136401303a99d7b0c845#1a471716951fdc5029dbe12eb74a4bbfa952c59c * The "imagethumbnail" preview type in Dolphin seems to feel responsible for _every_ image mimetype ( "image/*" ), see: https://invent.kde.org/network/kio-extras/-/blob/master/thumbnail/imagethumbnail.json So in combination with the camera RAW images plugin in place, checking the "Images (GIF, PNG, BMP, ...) " entry in preview settings now implicitly also covers RAW files even though one may have explicitly deselected the "raw image" entry. Not only raw files are affected: There is e.g. a separate entry for JPEG images in the preview settings. If I deselect it, thumbnails for JPG files are displayed nevertheless when "Images (GIF, PNG, BMP, ...) " is selected. So it effectivly does nothing unless one disables previews for all images. == Idea == Perhaps it would be good solution, if the imagethumbnail preview type would only apply to all image files _not_ covered by separate preview types (BMP, PNG, PCX etc; _not_ JPEG or RAW files)? == (Horrible) workaround == Deleting the file /usr/lib/x86_64-linux-gnu/qt5/plugins/imageformats/kimg_raw.so will stop new RAW thumbnails being generated (to remove the existing ones, purging ~/.cache/thumbnails should help). -- You are receiving this mail because: You are watching all bug changes.
