BETA: Shadows suggestion
I noticed you were adding a lot of shadows on frames that formerly didn't have shadows. I usually hide my actionbar backdrops and only show the buttons. So i added shadow to the buttons with something like this in my actionbar files:
-- BUTTON SHADOW
if C["ActionBars"]["HideBackdrop"] == true then for i = 1, Num do local Button = _G["ActionButton"..i] Button:CreateShadow() ActionBar1["Button"..i] = Button end end
` you also changed the border size to 1 pixel?
