kwin perf svg
SUMMARY
Kwin version: 5.14.3
After update and fresh system reboot I've noticed that rendering performance is
degraded.
Using top I found that kwin and plasma shell permanently uses 10-15% of CPU.
STEPS TO REPRODUCE
1. update to 5.14.3
2. reboot system
3. open shell to see top
OBSERVED RESULT
bad rendering performance and high cpu usage
EXPECTED RESULT
good rendering performance without lags

KDE Plasma Version: 5.14.3
KDE Frameworks Version: 5.51.0
Qt Version: 5.11.2-r1
ADDITIONAL INFORMATION
In attachments I'll provide perf.svg for kwin and plasmashell.
