The thumbnail for some .mp4 video files is just random noise, and in the preview panel they only play a white background.

Can't reproduce on git master, FWIW. Does it reproduce if you move the files to the Plasma desktop? Are the thumbnails messed up there too?

It's the same on the desktop.
But I also can't reproduce on the latest (kde-linux_202501230256) KDE Linux image, sorry for not checking beforehand.
