Why shared element transition make transparent Activity blank?

Question

I have a MainActivity containing a Fragment, the Fragment has a FAB button and clicklistener star a new Transparent Activity.
Transition works wellwith pairing views, but the Transparent Activity turns blank when I use ActivityCompat.startActivityForResult.

What's wrong?

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {

                ActivityOptionsCompat options = ActivityOptionsCompat.
                        makeSceneTransitionAnimation(activity, (View) fab, fab.getTransitionName());
                ActivityCompat.startActivityForResult(activity, intent, REQUEST, options.toBundle());
            }else{
                startActivityForResult(intent, REQUEST);
            }
