Cooldown frame overflow
 

I created a button with an icon showing a spell texture. If I hook a cooldown frame created "on the fly" to this button, there is a strange behavior: the cooldown overflow from the button as shown in this screen:



The Cooldown frame is created in this way:


Where
• icon = the button frame where the cd will be hooked

It's a Cooldown frame bug or is there a way around this problem? SetAllPoints() and SetScale() doesn't work.

Thank you in advance

EDIT: I discovered it's due to Masque Blizzard Skin. When Masque is disable, the cd is displayed well
