Bug ID: 504185
Summary: 100% CPU usage on all cores for no apparent reason
Classification: Applications
Product: digikam
Version: 8.7.0
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: digikam-bugs-n...@kde.org

Target Milestone: ---
SUMMARY
Hi, for a few weeks I've been experiencing this behavior, but I'm still unsure
what's triggering it. Basically, after a few minutes of using digikam, I notice
the computer getting sluggish. If I check the Taskbar, I see that Digikam is
using all the CPU threads at 100% usage (I'm using a Intel i7 5700X processor).
And it lasts for several minutes before it goes back to normal.
Initially, I thought it was related to the background face training and
scanning (although in my experience, it was much more light on resources), but
I disabled the 'Enable background face recognition scan' option, restarted
digikam, and the issue is still there.
These days I'm mostly tagging faces, but I don't know if it's related to that
or not. I can use DebugView and get the logs if you want, just let me know.
STEPS TO REPRODUCE
1. Use digikam normally, tagging some faces
2. Wait a few minutes. Observe CPU usage.
OBSERVED RESULT
- CPU usage at 100% for several minutes.
EXPECTED RESULT
- Normal CPU usage.
SOFTWARE/OS VERSIONS
