I agree that changing focus with alt-tab (or anything else) should disable the pointer lock, that the notification message is annoying and should go, and that "long press esc for 5 seconds" is not very obvious and probably should go too. I find myself agreeing with @hein that pointer lock should return if the client regains focus: if I alt-tab out of my FPS game to check my email, when I alt-tab back, it should work again (provided I haven't been killed during the email break lol).
  
  
  That's already the case.

  There is [Alt+F4] for killing misbehaving clients. Known to most people using a PC and documented in our keyboard shortcut system. In comparision hitting Escape key for several times to do something on the compositor level is not really better than long pressing.  The user still would need  to be informed about it somehow. We can't assume every user hits repeatedly (and fast enough) Esc when there is something not working. And what if I have to press Esc several times to quickly check a menu in game?
