Can you please check this happens on a new user account? Is there any other software running that might be automatically creating thumbnails and storing them in your /tmp folder. You *might* be able to see whatever is writing to the /tmp by using the iotop command from a terminal, but it's a very small file so it will be very briefly on the screen when it writes.

Is dolphin installed with as a flatpack, or snap, or otherwise contained ? Do you see thumbnails in ~/.cache/thumbnails in subfolders ?

I thought so the first time I had the bug, but I had kio-extras installed and also installing or uninstalling ffmpegthumbnailer/ffmpegthumbs makes no difference Reply at: https://bugs.launchpad.net/ubuntu/+source/dolphin/+bug/2087829/comments/10 ------------------------------------------------------------------------ On 2024-09-30T16:44:11+00:00 Kde-handler941 wrote: I am having the same issue as well, I did the same thing as I just took an screenshot using spectacle and saved it in /tmp and it immediately started creating copies.

I just don't know how to paste helpful debug output here, starting dolphin in konsole doesn't print anything helpful. All I saw was kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError kf.kio.core: An error occurred during write. The worker terminates now. and I'm not sure if this is related. So, how can I gather relevant debug output?

On my computer, I am using archlinux, and this issue also happens on my computer (filling my /tmp directory with endless jpg files every half second or so, maybe less) with the latest dolphin 24.08.2-1. I uninstalled dolphin for now, and I'm using krusader as my file manager. kio-extras was already installed prior, and did not stop or help it from happening.
