Dolphin images preview

Hello,
Is there a way to have working previews of images, videos etc in Dolphin? All option in Dolphin are enabled. Is there any dependences missing for Dolphin?
Can I install them on Bazzite?

Thanks,

Thumbnails work for me in every View Mode with Icons being the largest, what are you seeing there, is it a broken image or simply nothing?

Mostly those default icons. I tried every option with no luck.

Are you looking at local files or files on a server? I just figured this out for myself, SMB shares will not show image previews, you’ll need to mount the drive with CIFS or similar.

It’s on local disk. I have enabled preview for remote disk to check and did not help. I have installed Dolphin from flathub and previews works.
