SUMMARY In Dolphin, every links to files that have a preview have smaller preview that what they should have : smaller than original files preview. It makes harder to see those content with the same zoom level than non-linked files. STEPS TO REPRODUCE 1. Open Dolphin with previews turned on. 2. Open a folder that have a file that has a preview, like a picture. 3. Create a link to this file in the same folder (the name of the link need to be different). 4. Compare the size of the preview of the file and of the link to the file. OBSERVED RESULT Links to a file has his preview really smaller than what it is pointed at, and smaller than the space the preview has to be shown. EXPECTED RESULT The preview should take as much space than the preview on the original file. It makes harder to see what the content his, for no gain (- We already know that something is a link because of the link icon). SOFTWARE/OS VERSIONS Dolphin Version 25.08.1 Operating System: KDE neon User Edition KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 Kernel Version: 6.14.0-29-generic (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION Files that only show a generic icon are not affected by being a link or not. It only affect files with preview of their content. This affect previews in Dolphin for all three view modes (icons mode, compact mode, details mode) but it doesn't affect (outside Dolphin) previews on the desktop background. I thought I had already reported this bug, but I didn't found the report. What I submitted was some others bugs (bug 500624, bug 498211).
Created attachment 185195 [details] Screenshot of smaller preview size for linked files in Dolphin
This looks like the same issue as bug 499820 which had been fixed in 24.12.3 Note: The screenshot shows Icon View, the bug is seen with a .png file I'm not able to reproduce this on git-master. Previews have the same size icons as the original file, but I am able to reproduce this with Dolphin 25.08.1. The good news is this means it's fixed in the development version of Dolphin, and will be available on your system when Dolphin is updated to 25.08.2. If you still see this bug with Dolphin 25.08.2 or later, feel free to reopen this report. Thanks!
