What is in my screen when the bug occurs >>> http://i.imgur.com/tICNkVz.png
What happends: When pressing F7 the screen goes gray, it's still in 3D, that i know because of the names of the players and how they move.
What is the origin of this: I was messing pressing F7 like crazy and then accidentally pressed F8, the game crashed and relogged, when i got in-game the F7 mechanic wasn't working anymore.
How i solve it once: I opened the browser console and it got fixed instantly, no idea how i did it but it basically happend when i smashed my keyboard.
