"white noice" after resume from suspend

[Stuardo -StR- Rodríguez]

As a user, after I open my laptop to resume using it after it suspended by closing it, the background and some parts of some windows have this "white noice" instead.

I can get rid of it if I restart gnome (alt+f2 / r / enter) but it's still very annoying.

I'm using the latest nvidia driver 418
