Bug ID: 368846
Summary: System tray widget drains battery if tray icon's
pop-up tooltip changing too fast
Product: plasmashell
Version: 5.7.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: System Tray
Assignee: plasma-b...@kde.org
Reporter: network...@rkmail.ru
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
