When using this tool, my accent color gets reset periodically. Also, it randomly checks the "Use active accent color for inactive frames" checkbox when clicking save, even though I uncheck it every time. It is really frustrating, as it greatly messes with the colors. I also don't seem to be able to change any color via regedit, it just gets reset everytime I close the registry editor.
I'm using Windows 10 1909 (Build 18363.720)
