The bug occurs when I'm in the game not the launcher, if I have multiple tabs open and change to them then switch back to game, it causes my game tab to deselect as if I was on a different window and Esc Menu opens up, this will happen once every 10 seconds until I quit and reload the game or try random combinations of tab switching, no other programs have this bug and versions below 1.13 don't either, I've also tried running 1.13 and above from technic launcher and this bugs also occurs there.
