When playing, a mouse can go beyond the game and minimize it, exit or switch to another application, and so on.
It all started after switching to another computer, attached a screenshot where you can see how right in the game you can go to the taskbar, thereby minimizing it.
I already created a task on the topic of an error, but it was in a different language.
