This appears to be a culling problem. The only triangles that are
disappearing are those at the edges of your rounded cubes. My best guess is
that the rounded edges of the cubes are not tesselated enough i.e. not
enough triangles were used to define the rounded sections. Because there
aren't enough triangles, some of the triangles have normals that are not
quite correct and they are being culled. As you rotate the view, naturally
different triangles would be affected. To fix the problem, you need to
create the cubes with more triangles in the rounded regions. Hopefully,
your code can be adjusted to do that.
