Bug ID: 511935
Summary: Plasma 6.5 abnormal plasmashell CPU usage with
slideshow wallpapers
Classification: Plasma
Product: plasmashell
Version First 6.5.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Wallpaper images
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
Very high CPU usage for plasmashell (12-18%) when selecting slideshow wallpaper
with the ordered alphabetical option (A-Z, Z-A). The Order by Date and Random
options do not seem to cause issues.
It is worth noting that the problem seems to worsen as the number of source
folders for images increases (in my case, i noticed 8-12% with the default
usr/share/wallpapers, and 12-18% with another custom folder added).
STEPS TO REPRODUCE
1. Set wallpaper option to slideshow, with alphabetical order (A-Z or Z-A)
2. Open a resource monitor. I used Plasma's system monitor
3. plasmashell CPU usage is reported as 12-18%
OBSERVED RESULT
Abnormal plasmashell CPU usage, around 12-18%
EXPECTED RESULT
Should be around 1-3%
SOFTWARE/OS VERSIONS
Fedora Linux 43 6.17.7-300.fc43.x86_64
KDE Plasma Version: 6.5.2
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0
ADDITIONAL INFORMATION
I'm 99% sure this wasn't the case in 6.4, because I first observed the behavior
on my laptop with 6.5. Then I went to my desktop with 6.4, where i confirmed
the behavior was not present. I then installed 6.5 on my desktop too, and the
behavior did appear with 6.5 installed.
