Description pollux/ned 2024-12-02 06:11:26 UTC
SUMMARY
Some of my wallpapers thumbnails dont show properly in kde's wallpaper setting or desktop settings, wallpapers, they instead show a white image

STEPS TO REPRODUCE
1. Use some of the wallpapers i have provided that dont load thumbnails properly
2. Check dolphin, desktop wallpaper settings, wallpaper settings

OBSERVED RESULT
Thumbnails dont load on any of them

EXPECTED RESULT
Should show the thumbnails

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Endeavour os
KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0

ADDITIONAL INFORMATION
I feel like i may be missing some package for these thumbnails to load but i dont know what package i need, it would be nice if there was a popup saying your missing a certain plugin or package of somesort to get these thumbnails to load properly instead of having to go to the internet to figure out which package i need

Checking the arch wiki i have both kdegraphics-thumbnailers and ffmpegthumbs

One thing iv noticed with these images is that they show jpeg as type but then it also shows content as png image

while the other jpeg images dont show content as png image and they load their thumbnails fine

Hi - do those wallpapers show thumbnails correctly if you correct their filename extensions from .jpg to .png? Regardless of the extension they have, the content of the files is PNG images, so they won't display correctly if attempted to be processed by a JPEG thumbnailer.
