This bug makes the achievements button (the water bottle button) appear to be in the middle of the GUI, splitting apart the "Play" and "Settings" buttons. Oddly enough, the button also still exists in its usual spot down in the bottom left corner. I have adjusted my GUI settings to see if it made any difference and it, unfortunately, did not.
Thank you for your report!
