That's strange. I don't have the Gotham font installed on my computer, but I tried reproducing your issue with another font and I wasn't able to. It could possible be a driver-related issue. If you are on a Windows OS, can you check if you have updated the graphic drivers on your device by visiting the manufacturer's site?

I am using a macOS Mojave 10.14.1 and my Adobe XD is the 13.1.32.8. And I believe that there's no way to update the graphic drivers on macOS 
But you saying that you don't have Gotham font installed on your computer got me thinking "what if I change the font I'm using?" and boom! I don't know why, but Gotham is the only font that is bugging.
That's really weird.
But anyway, it worked! haha
