Description Patrick Tasse CLA 2016-04-08 14:01:26 EDT 
In the Control Flow view, the CPU in the tool tip of a process is calculated by finding the CPU that has its Current_thread equal to the process's tid.

For the swapper/n (tid=0) entries have been recently added to the Control Flow view, this computation is incorrect. When the CPU is busy in some process, the correct CPU won't be match, and another CPU that happens to be idle (if any) will be used to determine the CPU tool tip value of the other CPU's swapper.
