This nags one with the Rendering Problems window
How to fix: add these values to any values file (the filename doesn’t appear to matter, I use ids.xml, you can use an existing one as well, such as colors.xml or strings.xml)
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="visible" type="id"/>
<item name="masked" type="id"/>
</resources>
