Bug ID: 428195 Summary: Panel triggers constant repaints Product: plasmashell Version: master Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: System Tray Assignee: plasma-b...@kde.org Reporter: mgraess...@kde.org Target Milestone: 1.0 I observed very high cpu usage in kwin_wayland. Investigation with the show paint effect showed that KWin is constantly repainting the complete screen. By closing all application windows I could identify plasmashell as the offender (also high cpu usage but lower than kwin and confirmed by killing and restarting plasmashell). By making the panel auto-hide I could end the constant repaint, as soon as the panel is visible, one can observe the constant repaints again. I added an empty panel and added plasmoids untill the problem started and could identify SystemTray. STEPS TO REPRODUCE 1. Enable show paint effect 2. Make plasma panel autohide 3. hide/show panel OBSERVED RESULT the show paint effect shows constant repaint when enabled, which ends as soon as auto-hide gets enabled, restarts when shown. EXPECTED RESULT My notebook doesn't burn my legs :-) SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Neon Unstable Edition (available in About System) KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.75 Qt Version: 5.15.0 ADDITIONAL INFORMATION Obviously a Wayland system. When starting Plasma it takes a few seconds till the Problem emerges, the same is the case when adding system tray to a panel. If you have any question, please let me know.
