When you first press F3 after loading the game, the debug menu does not appear, only appearing once you press it again. I assume the code just initialises with `isDebugShown = true` meaning that you have to press F3 twice to get it to the actually-open state.

When you press F2 for the first time, does it successfully take a screenshot? Or do you need to press F2 a second time for it? Same thing for F1 toggling the HUD, I guess. (You may or may not need to restart Minecraft between testing each of these; it'd be interesting to know if you do need to)
No, doesnt happen with the other buttons. Also, its not only when I restart the game, it happends intermittently while playing.
Maybe MC-183776?
I'm not able to reproduce (If I press F3 after loading into a world after starting the game, the screen opens immediately). Does your keyboard have an fn key?
