Description

Product Version = Apache NetBeans IDE 9.0 (Build incubator-netbeans-release-334-on-20180708)
Operating System = Windows 10 version 10.0 running on amd64
Java; VM; Vendor = 1.8.0_162
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.162-b12

STEPS:

• Open project
• Minimize netbeans window or not have it in the foreground

ACTUAL:
Background CPU usage is constantly at 16-18%, so that my laptop fan turns on.  Does not cease unless I close netbeans or put it back in the foreground.

EXPECTED:
No background CPU usage when minimized or not the active window

I unchecked "Enable auto-scanning of sources" in Options->Miscellaneous->Files, but the IDE appears to still be scanning and constantly using CPU.

This issue was also present in version 8.2.
