Answer 1

Answer 2

Ctrl +h disable and enable the grid

Answer 3

Modular grid (Grid). Google, there is plenty of material. From the fact that I or someone else will write to you in 2 words what it is for, the picture will not change.
If you need to turn it off, then you have it as a separate layer and fill. Find yours - turn it off.
