swMs "sparkling "problem

hi all ~

Here is my question below :

In my case, I decode 3 channels and use swMs in "link_api_demos" 

and when it goes into "Chains_swMsGenerateLayoutParams(0, 3, &swMsPrm)"   ( it means "layoutId = 3 " )!  

it will show 3 images  and  the front 2 small images always sparkle  but behind image is correct 

thanks a lots

best regards
