Some full sreen issue

Hello, I have a problem in a full screen mode. For a minute after going this mode all is okay, but after a while Ш get this: my lovely hot corners doesn’t work and desktop switch animation disappeared. It’s pretty annoying, I hope someone could help me, cause I can’t find anything similar in the Internet. I’m using Elementary OS Juno and Atom deb package from official site.ezgif-2-a78b6b42ccf1

Okay, my gif was cutted, I don’t know why, but trust me

Here is a normal one, sorry:
