Dolphin freezes when file preview is enabled

Hello,

Since the Manjaro 25.1.0 Update (KDE Plasma), Dolphin always freezes when there are files in the current folder for which I have enabled file preview.
Dolphin simply stops responding, but there is no CPU load to indicate that anything is being loaded.

If I disable previews for file types in the settings, there are no problems.

I am currently using version 25.12.0 of Dolphin.

Is this a known issue and can anyone help me here?

Kind regards

Hi @Anomalie,

The only thing I can think of is clearing your cache:

rm -fr ~/.cache/*

Don’t worry, the contents will be regenerated as needed.

Hope this helps!

There could be an issue with some specific file types as they all require a dedicated “driver” to generate a preview. I would try to narrow down the specific file format making issues. For example HEIF or HEIC are not naturally supported as far as I know. Should normally not cause a freeze, but who knows.

You can configure previews for different file types in the Dolphin configuration, so you could experiment with turning off various types to see if you can identify a particular type causing problems.

You could also run journalctl -f in a terminal before starting Dolphin and watch for any errors or warnings.
