This works on the grid screen:
theme.GridScreenOverhangSliceHD = "pkg:/images/Overhang.jpg"
This does not work on the poster screen:
theme.OverhangSliceHD = "pkg:/images/Overhang.jpg"
However, this does work on the poster screen:
theme.OverhangPrimaryLogoHD = "pkg:/images/OverhangLogo.png"
Any idea why the overhang isn't showing up on the poster screen? It's showing the default blue gradient.
