Black and white squares remain after layer is hidden.

[Sarthak Ghule]

Hi,

I'm a novice in Gimp, so, sorry if the question is too dumb.

I added a layer in Gimp. After I clicked the hide layer button, the layer is vanished but what remains is something with black and white squares as shown in the image below. I want it to vanish, too i.e I want a complete blank background.

Thank you.
