Discord public test branch Bug

I don't know if this is the right place to write about this, prolly not but anyways, I'm on the public test branch for Windows 10 and i just discovered a bug. When I'm in windowed mode (not fullscreen) and right click on a server and go to notification settings i can't see the whole notification settings menu so i can't press for example done.

Some pics, First pic is the bug and second is how its supposed to be:

Thanks :)
