Issue when switching two surfaceview in sony bravia TV

In my sample app i have feature to swap one full screen player and small PIP player above full screen player , when clicking on swap button i need to swap content each other. Each player is sitting in different fragment. When switching i am changing the constraint with animation ` TransitionManager.beginDelayedTransition(layout)` . i am changing the `elevation` of fragment container to bring small player above big player on each swap operation. This is working fine when i set surface as `textureview` but i found that when i set surface as `surfaceview` , the small player which is shown above getting transparent on surface part. By setting `setZOrderMediaOverlay` true to small player it is fixed in other devices like Nvdea and MIBox but sony tv failed to pass with that fix.

i have changed the video renderer from `OMX.MTK.VIDEO.DECODER.AVC` to `OMX.google.h264.decoder` then its works but i cannot rely on software codec

any idea whats going on here ?

here is the sample code :
