Backdrop (in XML) doesn't show even after adjusting to 9.0 patch

[Kesselero]

Hey,

so im trying to get a backdrop of a frame to show up, I'm not getting any errors and the frame seems to load fine but without any textures applied to it.

I just copy pasted the example from https://github.com/Stanzilla/WoWUIBu...system-changes just to test but nothing happens.

<Frame name="TestFrame" parent="UIParent" inherits="BackdropTemplate">
    <KeyValues>
        <KeyValue key="backdropInfo" value="BACKDROP_TOOLTIP_16_16_5555" type="global"/>
        <KeyValue key="backdropBorderColor" value="LEGENDARY_ORANGE_COLOR" type="global"/>
        <KeyValue key="backdropBorderColorAlpha" value="0.25" type="number"/>
    </KeyValues>
    <Size x="300" y="300"/>
    <Anchors>
        <Anchor point="CENTER"/>
    </Anchors>
    <Scripts>
        <OnLoad inherit="prepend">
            print("Loaded!");
        </OnLoad>
    </Scripts>
</Frame>

Using /fstack I can click the frame in the center of my screen but no texture is showing

Thanks for helping!
