Clion started to behave very badly in last 2 days out of nowhere...!

Hey

This is quite crazy. It first started on my laptop. Out of nowhere, it started lagging. Typing was lagging, enter lag, copy-paste = forget it... 

I've updated to latter version, downgraded, went to stable etc etc. No luck. Its just lag like hell! That was on i7 8550 32gb ram laptop. No worries I thought when I get home I'll get on workstation 128gb ram, 2990wx cpu. Nope. the EXACT SAME ISSUES. 40% cpu usage on 8 file project with Qt library linked. I never ever had it before. Also 8 file project, eats 13GB of ram!!! 

What on earth happen ?! Did windows run some auto update or clion ? I'm lost! This app is unusable :O
