Bug ID: 356906
Summary: Irregular updates
Product: plasmashell
Version: 5.4.3
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kdde....@porcupinefactory.org
CC: bhus...@gmail.com, plasma-b...@kde.org
After running for some time (~2 days, hibernation may be at play here), widgets
start to draw updates irregularly.
Digital clock: most of the time, every 2 seconds (only other updates coming
from net/cpu/mem monitors), sometimes every 1 second, very rarely 3 seconds.
Task switcher: any updates happen only on 1 second boundaries, leading to
significant lag when selecting active window.
Reproducible: Sometimes
Steps to Reproduce:
1. Start KDE with the setup described in Additional Information
2. Use for a few days, hibernating between sessions.
Actual Results:
Digital clock: most of the time, every 2 seconds (only other updates coming
from net/cpu/mem monitors), sometimes every 1 second, very rarely 3 seconds.
Task switcher: any updates happen only on 1 second boundaries, leading to
significant lag when switching workspaces or selecting active window. (The
1-second boundary aligns with a clock bump, clock bump can be forced by
switching windows.)
Expected Results:
Digital clock bumps the number by 1 approximately every second when not CPU
starved
Task switcher never waits for a one-second boundary to update active window
highlight.
System uses Intel HD4000 GPU, default Fedora 22 setup.
When panel semi-transparent, underlying windows' updates imediately seen
"through" the panel yet the problem persists.
Panel setup: One of 2 panels; vertical. Widgets: CPU, mem, net monitor, task
manager, digital clock.
