When I press the windows start button while playing minecraft it crashed and also if I go out of fullscreen mode and back into it there is a bug that makes it so you can only see a small bit of the game! and another thing is when you have maximized it and want a large GUI scale the large is the same as auto & medium where I want it to be the same size as fullscreen!

when I press the windows start button I thought it would just minimize fullscreen! and when I go out and back into fullscreen mode I thought it would go normal! this makes it so there is no way to minimize minecraft without it crashing or you having to restart it anyway!!

windows start button makes it crash and going back to fullscreen mode makes it so you can only see a small part of the game (top left corner)

1. press the windows start button in-game and it crashed
2. go out of fullscreen then go back into fullscreen mode and you can only see the top left corner!
