I have a Roccat Vulcan 120. I only used it to decrease the brightness on the RGB because they are 100% if the program is not running. I uninstalled it already since uninstall/install doesn't fix it and Roccat does not know why its doing that.Interesting note, but the Asus X470-F is a known problem child with the 3000 series right now.
Tons of threads and comments all over reddit, asus forums, etc.
What keyboard software do you have that caused it in your case, out of curiosity?
Mine doesnt have software, so it wont help me, but i am curious.
