CPU usage at 100% while using Photoshop 2020 using any tool in refine edge

[Ricky5E64]

Hey,

since the last update my CPU is hitting 100% while i've been using the refine edge tools in Photoshop

I've done some googling and found something about CEPHtmlEngine  However I can't see that process running in Taskmanager and it's just Photoshop 2020 that's hogging all the runtime.

CPU is a 6600K I got 16GB of RAM.  Running 3 month old install of latest Windows 10

File size is 650ish KB (3005x4500 jpeg)  Can't Fathom it.  Program is completely unusable.

Using an Intuos (Bamboo Let's be honest) CTL-490 wired for input.  Tried uninstalling the driver for that and using mouse..Same results
