Summary: When moving the mouse over widgets with hover effects
(e.g. launcher menu items, system settings side bar)
CPU usage is higher than 150%
Classification: I don't know
Product: kde
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
When moving the mouse over widgets with hover effects (e.g. launcher menu
items, system settings side bar) CPU usage is higher than 150%
Interestingly - in Dolphin side bar, where there's also a hover effect (albeit
different one) - this doesn't happen.
STEPS TO REPRODUCE
1. Open system settings
2. Move mouse over the side bar (this also happens in many other places, e.g.
effects election in settings and info center)
OBSERVED RESULT
CPU usage as reported in top shoots up to more than 150%.
EXPECTED RESULT
CPU usage shouldn't noticeably increase - as is the case with Dolphin's side
bar.
