Clear cache ?

Yes, cleaning, iCleaner Pro

Not quite sure how to turn on and off , you would need to ask a theme developer but to remove the mask just delete it from its installed directory with iFile.

At that point, I did not set the mask, I did not do it for the theme, and the disabled in the plist, but the mask is still there

Your link is taking me to some crap where I win an iPad ?

No,this refers to a screen where the icons are shown there in the image below, it is clear the mask icon, it is small, but I would like to figure out how to remove it

I made a theme for iOS 9.3

After installation, the mask icon appears when you click on the icon in plist.info mask off

<key>IB-MaskIcons</key>
<false/>

How to turn off the mask? Any ideas?

Thanks!
