Section 5.9.7 of the spec states
UpscaledWidth = RefUpscaledWidth[ ref_frame_idx[ i ] ]
FrameWidth = UpscaledWidth
FrameHeight = RefFrameHeight[ ref_frame_idx[ i ] ]
RenderWidth = RefRenderWidth[ ref_frame_idx[ i ] ]
RenderHeight = RefRenderHeight[ ref_frame_idx[ i ] ]
Meaning FrameWidth must not be set to RefFrameWidth[ ref_frame_idx[ i ] ]
as we're currently doing.
