CRITICALITY

Low

DESCRIPTION

Overlay optimization does not work when resize processing is enabled on any 'Enabled' layer.

When any of the 'Enabled' layers has bit field DISPC_p_ATTRIBUTES.RESIZEENABLE as nonzero it will neither be optimized nor participate in optimization of layers below.

WORKAROUND

For optimization to occur for a particular layer, make RESIZEENABLE as 0x0. With multiple layers enabled, make RESIZEENABLE for all the layers as 0x0 for every layer to participate in overlay optimization of itself or for the layers below it.
