I can't minimize the Minecraft window in the first minutes after launching the game.

When minecraft is just starting, I can't minimize the game window for the first few minutes. This only happens if minecraft opens in fullscreen mode. Even the Alt+Tab keyboard shortcut doesn't work. If the game opens in full-screen mode, then minecraft cannot be minimized at all during the first 1-3 minutes. In the video, you can see how, when starting minecraft, I try to minimize minecraft through Alt + Tab, but nothing works. Fortunately, I had to wait a few seconds in the video, but often I have to wait for several minutes, and to be honest, it's really annoying.
