Android action bar menu item with icon gets smaller after 4.3 os upgrade

Question

Problem

Until 4.1.2 version, the action bar menu item with icon size is correct (attach 1)

with the upgrade to 4.3 version what is shown is the following (attach 2)

Code

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menuItemLogout = menu.add(0, MENUITEM_LOGOUT_ID, 0, "LOGOUT").setIcon(R.drawable.iv_logout);

    menuItemLogout.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    return true;
}

The icon

I attach the icon 85x48 painted with black so you can see it:
