Most recent Dec 8th JK build - Abnormally HIgh CPU

[dasp61]

Good Afternoon.

A few of our band members just updated to the most recent Dec 8th build of JK.  
The client app running idle or in solo/private session is using way to much CPU.
33% to 40% now, last build was 5 to 7%.   

I'm running on an Intel® Core™ i5-7260U CPU @ 2.20GHz  2.21 GHz 16M
Presonus 24C. JK and UC only, no other services.
Fully capable. 

My collogues running i7 Gen8's, all having the same high CPU usage issues.

Please advise.

Thanks
