Strange bug that makes Verve unusable

I just downloaded the program and was excited to use it until... I realized something was really wrong. This is what Verve looks like when I open it:

As you can see, the color wheel in the top right is a square. The canvas is black, and I am unable to change that. And the worst part is, I am unable to change anything about the brush other than its size. I have all my drivers up to date, and a modern graphics card. I am not sure what could be the issue. Any help would be greatly appreciated!
