I'm using plasma5 with knemo 0.7.7. I'm not sure if it is a problem of plasma or knemo, but if i configure knemo to show current download speed in it's tray icon pop-up tooltip, plasmashell would start taking 5-7% of cpu time while idle, even if tooltip and knemo icon are hidden. Removing systemtray widget, or removing download speed from the list, drops cpu usage back to 0-2%, which saves battery. This didn't happen with KDE4 Qt 5.7, KF 5.24, Plasma 5.7.3, openSUSE 42.1 Reproducible: Always Steps to Reproduce: 1. Make sure knemo daemon is running 2. start kcmshell4 kcm_knemo 3. In knemo's kcm dialog switch to 'tooltip' tab 4. Add 'Bytes received, bytes sent, download speed, upload speed' to 'active' column 5. Apply changes Actual Results: CPU usage for plamashell process rises up to 5-7% on i5 2410M
i think it's a client related problem: if the application changes its icon too often, it will generate a lot of dbus traffic, and there isn't much we can do about it
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I will be closing this bug.
