Problem with swmosaic window residue

Hi,

We are using 816x with 5.03 SDK

I have follwojng chain : h264dec->Dei->swmosaic->display

I am using DEI scaler to dynamically resize window and move window to arbitrary size and display it on one of the swmosaic window.

The scaling and moving working , but the problem is that if I scale window to a smaller size I see the previous frames from a previous size in background.

Looks like the swmosaic window "remember" the previous picture size , these only refers to size and not to a position.

To move and resize I do following :

1. Change resolution OMX_TI_IndexConfigVidChResolution in DEI

2. Call OMX_TI_IndexConfigVSWMOSAICCreateMosaicLayout with new window dimension and position on SWMosaic component.

What could be the problem with these ?
