Snackbar hidden but appears to be still there

I have a Snackbar div not visible but affecting the mouseover event on the grid “below” it. Is there a workaround to hide it completely?

There is not enough information to determine what the proper solution is.

One way might be to set the z-index property so the Snackbar is “behind” the grid.

If that doesn’t help, I may ask you to send me a minimal project which reproduces this.
