Typing the letter "r" in a textbox, either chat or commandblock gui, freezes the game and it also unfocuses the textbox! You have manually click the textbox again to continue typing.
I am using a QWERTZ Keyboard, and the language in Minecraft is set to English US. But it doesn't really matter because even if the language is German the same problem occurs.
Here is a HD video of it:

UPDATE:
Same problem appears with a Surface Pro when typing "r" in a command like this: /execute @e[type=armor_stand] -> it freezes at both "r".

INFORMATION:
When my UI profile is "Classic" and I then press "r" in a textbox it also switches me to the UI profile "Pocket". Maybe this will help?
