New desktop opens automatically?

I have a problem.

Quite often (mostly when I play Minecraft) a new desktop opens automatically and I fly out of Minecraft.

After a short time I can switch back to my normal desktop and thus go back to my game, but it's very annoying, especially when you're in the middle of PvP.

Does anyone know what's going on and how can I disable it?

Maybe you press Ctrl + Win + D while playing PvP

That just adds a new desktop

If not then you can reinstall Minecraft or write to support

In an absolute emergency, you can program your own OS with no virtual desktops xD
