Hi,
let me ask one thing before: why do you need that combo with visual styles when you can have that always in the upper-right corner like here:

This is more close to your drawing area (modelspace as well as every viewport).
I do prefer this way to avoid too many icons in the QAT, otherwise it wouldn't be "QUICK access toolbar") 😉 Maybe it's for you ok too.
Back to your wish:
>> "Visual styles" (I mean a combo box) does not appear in the quick access bar after placing it there and clicking "Apply"?
I know that some controls can be placed into the QAT, others not.
I'm currently wondering that you got it placed in the QAT, may I ask you what's the exact name of the Visual-Style combo that can be placed into the QAT? I don't find any one showing the combo-list of Visual-Styles that I can place into the QAT.
A thought about something disappears from the QAT: I guess when you push too many controls (especially the combos which are quite wide then Autodesk might react in case of smaller app-window size with removing them to make sure a bit from the filename centered in the upper application window frame stays readable.
So if you reduce the app-window-size I can imagine that AutoCAD removes items from the QAT ... but just thoughts, never tested this!
