The window of Minecraft is buggy

I don't know how it happens and how to explain it well, but when I'm playing Minecraft and when I press few keys at once something's wrong with the Minecraft window. Sometimes it shows the screen that is showed when esc key is pressed, sometimes the window just tried to reposition itself and the border of that window with Minecraft opened is white, but I have dark mode applied. This bug makes the game unplayable.
