I can play Minecraft normally, but when I switch to my browser, in this case Google Chrome, my Minecraft says "Not responding". If I'm in a server I can still see people talk and stuff, but I cant do anything else then close Minecraft.
It will then go to the launcher and I have to start the game again.

Game ended with bad state (exit code -805306369)
This is the only error it gives me in the console.
And it says Ignoring visibility rule and showing launcher due to a game crash
after that.
