Supernova (115.2.3) high CPU Usage
When Supernova 115.2.3 starts up the CPU usage goes to 11-14% until the calendar brought into focus and then CPU usage drops to less than 1%. This problem exists on all up to date Win 10 Lenovo i7 PCs on which Supernova 115.2.3 is installed - it is not unique to one PC
There were claims that this issue would be fixed in version 115.2.2 BUT now in version 115.2.3 it still exists.
See before calendar and after calendar focus images of task manager
Will this issue be address soon?

I uploaded a short profile. The recording begins with initial message tab start state of Supernova followed by the action that brings the calendar tab into focus and finally back to the message tab
This problem has yet to be resolved. Did you see the profile I provided? The attached images show the CPU utilization before and after bringing the Calendar into focus
