--- Comment #2 from Akseli Lahtinen <akselmo at akselmo.dev> ---
This is likely due to having both KDE thumbnailers and "standardized"
thumbnailers ( /usr/share/thumbnailers ) for same mimetypes.

We should check for this list if we already have our own thumbnailer for the
mimetype, and if so, hide the ones from /usr/share/thumbnailers for this
mimetype.

Sadly it's bit more complicated than that, and moving our own thumbnailers into
this standard should help more gradual settings for them.

Still, can confirm the issue.
