Bug ID: 502587
Summary: Plasma Animations causing Full-Screen Repaints
Classification: Plasma
Product: plasmashell
Version: git-stable-Plasma/6.3
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-performance
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: 1.0
SUMMARY
Various plasma animations such as progress bars, timeout indicators, or
notification paging transitions cause full-screen repaints. Overall Plasma
Shell is very eager to cause full-screen repaints.
Can cause micro-stutters and slowdowns, especially for long-running animations.
I'd guess it would probably hit battery life on mobile devices, too.
STEPS TO REPRODUCE
1. Enable the Kwin painting effect
2a. Begin a large file transfer (or some other event to trigger an ongoing
progress animation)
2b. Open the "Hidden Icons" area of the system tray and move your mouse over
various buttons
2c. Trigger any transitions, including opening any popup-based widget (menus,
tray items, etc)
OBSERVED RESULT
The entire screen repaints
EXPECTED RESULT
Repainting should be limited to just the progress bar, or the popup surface
SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION
