Thanks Xrystal, it's working! MiniMapTrackingBorder doesn't work, but after doing another /framestack I realized the object is MiniMapTrackingButton (which doesn't appear at all in Minimap.xml ). Taking what you said (adding Border) gives me the right object (MiniMapTrackingButtonBorder).

Looking again at Minimap.xml, I see the frame after MiniMapTracking is named $parentDropDown:

<Frame name="$parentDropDown" inherits="UIDropDownMenuTemplate" clampedToScreen="true" id="1" hidden="true">
...
    <Button name="$parentButton">
    ...
        <Layer level="BORDER">
            <Texture name="$parentBorder" urgency="5" file="Interface\Minimap\MiniMapTrackingBorder">

Does MiniMapTrackingButtonBorder equate to $parentBorder of $parentButton in this case? Aside from doing an /fstack on the Mninmap and finding MiniMapTrackingButton, how can one tell that $parentDropDown leads to the tracking button border (assuming it does)?
