Bug ID: 499987
Summary: ICC Prefer efficiency setting, worse performance on
stable release, and artifacting.
Classification: Plasma
Product: kwin
Version: 6.3.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: performance
Assignee: kwin-bugs-n...@kde.org

Screenshot of window border shadows.
STEPS TO REPRODUCE
1. Set color accuracy to "Prefer efficiency"
2. Move a window with shadows around borders.
OBSERVED RESULT
Weird dotted artifacts.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 6.3.0
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.2
ADDICTIONAL INFORMATION
Other than the dotted artifacts on shadows when moving windows with the
preferred efficiency setting that was not there during the 6.3 beta. Now the
prefer efficiency setting does not yield the same performance improvement it
did in the 6.3 beta; it's slightly less efficient now on 6.3.0 stable, it's
quite noticeable. This has to be a regression or something somewhere because
during the beta I used this setting the entire time experienced literally no
frame drops, but now I am.
