scaling object down cause font to become blocks

The scale of our project changed because of Vuforia fusion and AR kit. How can I make my TMP button scale down without becoming blocks? See attached video.

 

Most likely this is an issue with the amount of padding used when the font asset was created. See FAQ Question 2 and 11.

P.S. There are other possibilities like making sure the scaling of the text object is uniform but let's start with these.

 

Thanks @Stephan_B ,
I understand font asset creation better now. It turned out the size and scale of my canvas was interacting with the issue. I can now reach my target scale.
