Bug ID: 528073
Summary: Dolphin CPU usage spikes when opening a folder
containing an incomplete torrent video
Classification: Applications
Product: dolphin
Version First 25.12.3
Reported In:
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: panels: folders
Assignee: [email protected]

Target Milestone: ---
## Description
When I open a folder containing a video file that is still being downloaded by
a torrent client, CPU usage rises to about 100% and stays high. The behavior
appears to be triggered by opening that folder. I suspect Dolphin's video
thumbnail generation or a thumbnail helper is repeatedly trying to read the
incomplete file, but I have not confirmed which process is consuming the CPU.
## Steps to reproduce
1. Start downloading a video via a torrent client and leave it incomplete.
2. Open the folder containing that partially downloaded video in Dolphin.
3. Observe CPU usage while the folder remains open.
## Expected behavior
Dolphin should show the folder contents and either generate a thumbnail
successfully or give up on the incomplete video after a reasonable attempt.
Thumbnail generation should not keep a CPU core busy indefinitely.
## Actual behavior
CPU usage rises to approximately 100% and remains high after opening the
folder. The issue is currently occurring on my system. Closing the folder or
disabling thumbnails may help determine whether thumbnail generation is
involved.
