This issue was reported here as a bug. I have personally experienced this with one of my apps. Setting the topMargin for the toolbar works for me. As somebody commented on the bug report, here is the fix, as a function from the issue report.

private void fixApi21ToolBarBug(Toolbar toolbar){
    if(Build.VERSION.SDK_INT!=21) return; //only on api 21
    final int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
    final int result = (resourceId > 0) ? getResources().getDimensionPixelSize(resourceId) * 2 : 0;
    final CollapsingToolbarLayout.LayoutParams params = (CollapsingToolbarLayout.LayoutParams) toolbar.getLayoutParams();
    params.topMargin -= result;
    toolbar.setLayoutParams(params);
}

See the result here.
