You can still achieve it, with interface textures:
Taken from Aurora, place the folder Tooltips in your Interface folder: Interface/Tooltips/
You have to restart the game to take effect.
Note: If you are using this texture files. You are forced to use the texture, you cant disable it via any AddOn.
Code: Select all
World of Warcraft \ _retail_ \ Interface\ Tooltips ChatBubble-backdrop.blp ChatBubble-Background.blp ChatBubble-Tail.blp
Thanks to discord user Alea for pointing out that we can still do it like this. =)
