I am working on an app but I encountered a problem, if I place multiple cubes one over the other, somethimes small white pixel appears.

Does anyone know how to get rid of them? The cubes are the same size.

You need to pay attention to see them on this picture, but are very visible on phone.

I was adding the exact same values on X and Z, I was only modifying the Y axis by adding +1. Note that the cubes had the height = 1. But I managed to hide those bleeding by adding -0.0001 on X axis every time I added a new cube. As you said, I changed the X values by summing the initial position with a -0.0001. Althought, it’s not what I wanted, it fixed my problem.
