Whenever I make changes in source code(cluster_guages.qml) , black rectangle gets added at center which is blocking content which I am adding at center. its not visible in QT creater also. its difficult to debug.

I am building image by using "time bitbake agl-cluster-demo-platform" and installing .vmdk file in virtual box. animation is working fine. but black rectangle creating issue.

please provide the solution.

also provide agl-shell-client-protocal.h file to debug this in qt creator. file is not available in package.
