Menus are invisible

Loading in to the main Minecraft page goes smoothly. One thing to note immediately is that my avatar on the right side of my screen is invisible. Any option that I choose on the menu turns every button and input on the screen invisible, and all I see is the background map spinning in circles. If I try, I can hit the invisible buttons, but even if I load into a random world I find, my crosshair is missing, and all of the buttons on the screen are missing.
