Hi,
in the past I had Dolphin show Thumbnails for images, such as .png files. Today I notice that they only show as gray boxes in the “Icons” view.
The “Preview” settings seem to be missing a lot of selection options, screenshots from others suggest there should be ones like “JPEG Images”, “Images (GIF, PNG, BMP, …)”.
I read KF5 Dolphin Thumbnail Support Yet? but already have kdegraphics-thumbnailersinstalled.
Would appreciate any ideas. This is on Tumbleweed and I mostly use Sway.
All there for me (see screenshot) , using KDE Plasma on X11 … plus, I have waaaay more Preview choices compared to yours - notice, there’s a scrollbar on right, indicating even more choices. And no special packages installed here for that.
A couple of things to try
Login using KDE with X11. Now try Dolphin, Any change?
If no change, create a new user account (that’s never been used) on the system. Log out of your main user account, then log in using the new user account. Fire up Dolphin. Any difference?
.
