This makes the game unplayable for me. My cursor wandering onto my second monitor and kicking me to the main menu has caused my character to die several times due to the lag of my having to move my mouse back to my primary screen and click "Resume Game". Please fix this. I just got this game and for it to be unplayable due to a completely fixable issue is disappointing, to say the least.
This issue was reported almost two years ago, and there's STILL no resolution? I made the mistake of buying the Win10 version from the Microsoft App Store and they won't refund my money even though I have expressed to them how this is broken and a known issue. C'mon Mojang, help your customers here!!!
