Description andrei.grg 2016-10-19 11:25:07 UTC 
Moving the mouse in random pattern around the screen causes high CPU usage.

Reproducible: Always

Steps to Reproduce:
1.Open Konsole
2.Open Htop
3.Move mouse fast in random patterns around the screen

Actual Results:  
Effect:
All CPU Cores are going up to around 20%. Every opened GUI component seems to spike the CPU. Konsole, plasma, chrome, dophin, etc. 

RealTime effect:
Can cause short mouse freeze when working with applications that are CPU intensive.

Expected Results:  
Insignificant CPU spike or none.

If chrome also spikes, then it isn't a Plasma issue.
