Font looks different when I change the size in UMG...

Hello! :slight_smile:
Can someone explain to me why my font become squarish between size 6 and 16, the 17 one is also different? Before 6 and after 17, it seems to be okay. I tried the Bold and Italic version, it works good at any size.
It’s exactly the same font, regular version, the same file, just the size is different in my screenshot.

Thank you!
