beta client bug

so heres how it happened. I joined a game and I noticed that the client was a bit larger than my laptop screen so i shifted it over and thought it was ok. I then realized that it had just cropped the client??? I didn't notice at first thought they changed he chat or something but i just couldnt find the chat so, I just got into a game and asked people in the chat where the chat was. They told me to look on the right and i was like "theres nothing there". Turns out whenever i open the cliet and shift the tab the chat gets cropped out
